RAID question: how can I renew the data in raid array?

Q: RAID question: how can I renew the data in raid array?

hello everyone,

I am thinking to renew the whole data in current raid1 array md0. My environment is:

raiddev /dev/md0
raid-level 1
persistent-superblock 0
chunk-size 16
nr-raid-disks 2
nr-spare-disks 0
device /dev/hdb1
raid-disk 0
device /dev/hdd1
raid-disk 1

this '/dev/md0' is /home, so I'm not booting from this disk and the other file systems including root and /boot are on /dev/hda.

What I want to do is to renew the whole data in /home.

Is there any way to do this by switching /dev/hdd1 with all new data copied, then sync this new data to the other raid disk (/dev/hdb1) : FROM /dev/hdd1 (the disk just added with new data) TO /dev/hdb1 (currently active raid disk)??

Usually, after switching the HDD to new one, data in /dev/hdb1 is to be copied to /dev/hdd1 for recovery. But in my case, I want to do the opposite.

I would be so appreciated by all your helps,
Thank you,

Preferred Solution: RAID question: how can I renew the data in raid array?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: RAID question: how can I renew the data in raid array?

I'm not sure what you want to do.. You want to copy something to the /dev/hdd disk (from another computer maybe) and then copy the data from /dev/hdd to the RAID array?

Since you are using RAID1 then it should be fairly simple.
You just simulate disk failure by removing /dev/hdd. You could do this by making the hdd drive hdc instead (jumper it to be the secondary master). Now you mount the "hdc" drive (that really was you hdd) and copy whatever you want to /dev/md0.
Since it's a RAID1 array then all the data that goes to md0 is written to hdb and when the /dev/hdd comes back the RAID is syned onto both disks again.

I'm not sure if that makes any sense to you. Can't be less obscure than your post though

Guys,

Is it possible to use a separate hard disk for your OS and programs with data storage on a RAID Array consisting of two (or more) identical hard disks?

Would the system disk need to be the same size as the disks used for the RAID Array?

Thanks!

Hi all,
My RAID 1 (I think? I have two equal drives that are mirrored) array was causing me a lot of pain. It kept freezing up my system and having me to had to rebuild the RAID too often. After a number of tests and browsing info online, I've decided that the RAID was the culprit of the freezing and BSODs that came once in a while.

Before deleting the RAID array, I went and used the Seagate (my HDDs) .iso file and used their diagnostic tool to check the drives. I did a long test of one of the HDD (Device 1) and it passed. I deduced that this was at least a good drive. I didn't do a long test for the other HDD (Device 0). But with both, after a short test, both passed.

I then went into the RAID manager (DOS-looking screen before Windows starts) and then 'reverted' Device 1 to non-raid. Then decided to choose 'delete RAID setup' for the Device 0. All good so far. I rebooted and Windows actually started fine. This is where I'm at right now as I type this. No freezing so far!!!

What I wanted to know is how do I find out which HDD Windows is booting off from? Is there a command line I can use in command prompt window in DOS mode to find out this info? It'd be great to know that I'm not on Device 0 since I haven't done a Seagate diagnostic long test on that one.

Also, I'd ideally want to have the second (Device 0) HDD formatted so that I can leave it in my tower and use it as an external HDD with Syncback. This is the closest thing I can have to RAID and I'm perfectly happy ... Read more

A:RAID - deleted RAID array, Windows 7 ok but I have questions

You can do into Disk Management and it will tell you which drive is used for booting. It will say it is active.

I am confused as to one part. You say you want to leave the second drive in your computer, but use it as an external. You can use one as your main drive, and use the other for backup...however a good backup process involves a drive that isn't readily available all the time. That being said, something like SyncToy from Microsoft will allow you to choose folders and on a schedule or manually, copy them to the second drive. I use this on my wife's laptop to keep her photos backed up to our server.

RAID has no place on a desktop system, so you are better off without it. But to get started, just go into Disk Management to see how your drives are configured now. Post a screenshot if need be.

My mum recently gave her computer to me since she got a netbook and thought that she wasn't getting enough use out of such a computer. An error message kept showing up when I powered on the computer, apparently this had been showing up for some time.
It was on the Intel Matrix Storage Manager before Windows started, one of the physical disks were listed in red. However, the computer was still in full working order, but I wanted to get rid of the screen that kept coming up, so in an attempt to fix it, I went into the Matrix Storage Manager's configuration utility and not knowing what it would do, reset the disk listed in red to Non-Raid.

Now ever since I've done that, I've seen nothing except the BIOS, all that comes up after the Matrix Storage Utility now is a device listing and it says at the bottom 'DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER'. I inserted an OS disk and nothing would come up. Since then, the closest thing I've had to progress was by going into the BIOS settings and changing the hard disks SATA mode to 'IDE'.
After setting it to that, the Matrix Storage Utility doesn't show up, which I thought was a good sign at first, but then afterwards the same final screen shows up, but the message at the bottom had changed.

Hello!

My setup was the following:

60GB SSD - win7 64bit
3TB RAID0 array - data

I needed to break down my RAID array so they could be accessed by two other OS. Once I broke down the RAID, Win7 fails to boot. It goes into constant reboots. The thing that REALLY confuses me, is that the OS should not care about my RAID array. The OS was specifically installed to a completely different hard drive. On a different bus.

Any help/explanations/ideas would be a lot of help.

Hi all. I'm interested in setting up a RAID 0 array in a computer that already has one drive in it.

Here's the question:
Can I set up the array without having to re-format the existing drive? I really don't want to have to back up all the data on the drive I already have.


Thanks for any help.
 

A:Question about setting up a RAID array

After a little bit of research, it appears you "may" be able to add another disk and RAID 0 it without deleting your data. Some Intel SATA controllers do this. Do you have IDE or SATA RAID? And what is the RAID controller?

But it appears the operation is fairly risky, because at some point it is going to have to be deleting data during the migration. One way or another. And if it fails in the middle...

My advice would be to backup your data and start with a fresh emtpy RAID.

I couldn't find an appropriate forum for this question, so I hope it's ok to post it here.

I have a Sony Vaio AR51SU.
It comes with 2 x 250GB hdd's in a raid 0 array.
I would like to delete the raid array and have the discs seperately. That is the easy part. I can just delete the array in the bios settings. My problem arises when I want to re-instal the OS. If I use the system recovery method I'm reasonably sure that it will replace the raid array, by default. I have made the backup recovery disc but I suspect that will do the same thing. Would I be right in that assumption?
I'm also not sure that Acronis TI would handle it properly either.
Any suggestions would be welcome.
Thanks.

Has anyone experienced this on this IDE RAID kontroller(128MB cache)? I got a 1TB raid-5 array(6*200GB Seagate Barracuda) and its been up for like 1 month.

One time after a reboot it started hanging on initializing the board, and i got a bit worried that it was initializing the array and escaped it and proceeded booting w2k3.

A week after i set up weekly synch of the array as recomended from the maintanance chapter in the manual. It started yesterday evening and took a heap of time.

Today around 12:30 i had to shut it down to retreieve a 250GB SATA HDD that mounted as a stand-alone disk on the server for moving data, before delivering it to a warranty exchange. Afterwards i started the server, went out and came back 6 hours later.

The the synch said 89% and a worrysome popup message told me the driveletter on which contains the whole raid-5 array was corrupt and i needed to run chkdsk on it.

I let the synch(not same as init array, big diff ) complete and then ran chkdsk d: /f /x and it started correcting a heap of records and recovering a lot of files.

At the end i had lost 100GB of data and i was almost paralized... this wasnt supposed to happen on a very expensive raid controller.

Does anyone have a real clue of what happened here and how i can prevent it from happening again? I hadnt come around to get a good backup solution running yet and it seems ive misplaced my trust on this raid controller.

A:Lost 100GB of data on a Promise SuperTrack SX6000 Raid-5 array!

How many disks do you have in the R5 array?

This may be a difficult fix. The R5 can recover if one of the HDDs goes south, it can rebuild the data. But in this case, chkdsk would have looked for "data errors" which would have ultimately spanned the whole thing. Meaning your fix may be the use of data recovery software. Some simple software such as these come to mind:

Recover My Files - http://www.recovermyfiles.com/

PC Inspector File Recovery - http://www.pcinspector.de/file_recovery/uk/welcome.htm

Easeus Recovery software - http://www.easeus.com/

I can't say off the top of my head how well they handle large volumes like 1tb or RAID setups. But I use them for recovering data on single HDDs all the time.

I'm assuming, though, that the RAID itself is intact? And that it hasn't been broken to individual disks? If so it needs rebuilt right quick. But I'm no expert on RAID for sure.

Good luck

A:New RAID Array and Clean Install Win7HP-Help with RAID Driver Install

The pre-install driver will allow setup to install the files correcty on the RAID array this is offered for XP only.

When you have created the RAID array in the BIOS Utility and you launch the windows 7 setup does it show the new array as a possible install location? If so there is no need for a pre-install driver (Win7 supports a variety of RAID setup out of the box).

If you do need a pre-install driver, you have not been offered one for Win7/Vista on the Manufacturers website. The only solution to this I have found is to Download "7lite/Nlite" and build the "post install" driver into the win7 image then burn a new disk (or burn to USB pen for faster install).

Hi Everyone,

I have just cloned a RAID array and I am concerned about it's performance.

A bit of background...

My Motherboard = ASUS Z9PE-D16
RAID Card = PIKE 2008 LSISAS RAID card

The initial RAID array consisted of 6 x 1TB Seagate Constellation (ST1000NM001) SAS drives in a RAID1+0 (10) configuration.

The new array consists of 6 x 4TB WD SATA drives in a RAID1+0 (10) configuration.

Initial performance is quite slow, but this may just be due to parity checking. On paper the original, and new drives are comparable.

Whilst the original drives were SAS and the new drives are SATA they both operate at 7200RPM and have 6Gbps interfaces.

My question is - "Is my initial slow performance likely due to parity checking, or will I experience ongoing slowness?"

Any help here will be greatly appreciated. Furthermore whatever you offer with regard to help may assist a piece of Australian Cultural heritage!

Kind Regards,

Davo

First time posting :blush:,

Situation: I have two hard drives : main drive: Seagate 500GB w/ windows xp and second drive: WD 1TB blank.

Without backing up the main drive (ops...), i went ahead and enabled RAID 0 on both drives and created a RAID volume (128KB strip / Size: 1TB (931.5GB)).
NOTE: the RAID volume size is only showing the exact space of the 1TB, excluding the 500GB drive.
After realizing that I needed to create a backup image of my main drive to use RAID with an existing drive, I'm left with the "Operating System Not Found" message.

Question: If I Delete RAID Volume (which is based on the size from the blank 1TB drive), will both drives become available as non-RAID disks and keep the original data on the 500GB main drive and be able to run windows again?

I'm using software RAID through Intel Matrix Storage Manager option ROM v5.6.2

I understood that "Resetting the drives to Non-Raid" will cause all data on the disk to be lost, so this isn't the approach that I'll be taking til I find a solution to backup my data.
However, from reading the "Delete RAID Volume" option, it listed Deleting a volume will destroy the volume data on the drive(s) and cause any member disks to become available as non-RAID disks, so knowing that the RAID Volume is blank, then maybe trying this will be the answer.

A:RAID issue - deleting RAID volume to restore non-RAID disks

sadly, there's no way to do what you want without an existing backup.

Look at it this way;
A disk has a container ~ the partition.
The partition as a structure ~ the filesystem (eg NTFS, FAT32, RAID).
We put our data into the structure.

When we create backups, we are getting only the data itself (unless you use an image program like Ghost or Acronis where you get all three).

Deleting the RAID will give back the two independent HDs, but also breaks the structure so that the data becomes in accessible.

I am getting ready to set up a RAID Array but this is my first time doing anything with RAID. I know how to get into the BIOS and change settings and I know with two hard drives, I should do RAID 1. However, I just have a few questions before I do this. First off, I am an idiot and did not notice that my first hard drive I got when I built the computer has a 32 MB Cache:

Caviar Blue 1TB 7,200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive WD10EALX - OEM

I noticed it only had a 32 MB CACHE when I went to get another one. I then asked for the version with a 64 MB CACHE (WD1002FAEX), paid for it and left. Will these two hard drives work together in RAID if they have different sized caches? Please give me any info/experience you may have with this or anything with RAID would be helpful, thanks.

A:Help w/ RAID Array

The short answer is yes, they'll work. Onboard cache is internal to the drive, and as long as the drives are the same size, then RAID 1 (mirror) should work fine. I don't think it would make much difference, but the drive with the larger cache should be the primary drive just for efficiency's sake.

I just made a 2-drive raid array on my kid's computer like this:

Iwill KK266 motherboard with 1.4 ghz Athlon, 256 PC133 ram.
Promise Fasttrak66 raid controller
Two IBM 8.4 gb ata33 drives, each a master on its own channel.

I fired it up, and made a raid 0 array with the two drives, 16 gb total, 64 kb stripe.

Ran the Windows XP Pro install CD, and created two partitions on the array of about 8 gb each, and installed WinXp on the first one, formatting it with NTFS. It took a LONG time to format (well over an hour)

Once the Windows desktop was running, I installed a few more programs. The ATTO disk benchmark showed transfer speeds in the 17000 range for the C: drive, so I thought all was well.

But then I noticed I only had less than 700 mb free on the drive! I checked the size of what was installed, and found it to be just over 1300 mb, giving a total of just under 2 gb. These figures are shown on the drive properties screen.

Next I fired up the Disk Manager in the Administrative tools, and it showed both partitions in their correct size of 8 gb. No clue why I was only apparently accessing 2 gb of the C drive.

I then tried formatting the D drive, but after another long process, the format failed. No reason given.

What's going on?? I seem to recall there was some sort of 2 gb partition limit in FAT, but I'm using NTFS.

Can anyone shed some light on this? Am I missing something obvious?

Most cards that support RAID1 will allow you to use two hard drives that are not identical. The smaller of the two capacities will be the size of your RAID1.
ie: Drive 1 = 998GB and Drive 2 is 1TB, the RAID1 size will be 998GB

Backup all of your data, make sure that you have backed up all of your data. Remove the array configuration, get out your Windows DVD, reinstall the OS, patches, and all applications, copy your data back from your backup.

If I have to I will set it up with both a raid 0 and a raid 5 to have the best of both worlds but if I can get the array to take the 4th and migrate whatever then I will leave it with just the raid 5 setup.

My dad wants a new PC built - he wants a half-decent one, he only surfs web , music and streaming videos - he plays Flight Simulator X but thats all...

his current setup is:
3Ghz Pentium 4 with HT

160Gb SATA-II / 8Mb cache
nVidia 6200GS / 256Mb / 300Mhz
Windows XP SP3

now where thinking
Core2Duo (or quad if cheap enough)
2Gb Ram
2 x 160Gb SATA-II drives in RAID array
better nVidia graphics card
Windows 7

my question is this: WHICH IS BEST RAID ARRAY TO USE?

the reason we decided to use these method is for extra performance - now im aware that RAID '0' stripes the data so if 1 drive were to fail then he would have to re-place it or re-install windows on single drive - but you get the most free space and best performance from this...

what about MIRRORING? as he doesnt use much space anyway would he be best with this option? DO YOU STILL GET THE SAME PERFORMANCE FROM MIRRIRON AS YOU DO WITH STRIPING? (except you get less space but if one drive fails everything will still run off other drive....)

his disk usage would only be about 40Gb (without mirroring)

if you DO get the same performance with mirroring then how much space would he get from 2 x 160Gb...? (and installs obviously use double)

would he still get 320Gb with the 40% performance increase from raid'ing two drives together - just installs are double? (thats fine in that case he would only use 80Gb of the 320Gb which leaves him AMPLE)

Hello:
I am having a problem with setting up a Raid 1 array. I am using Windows Vista Ultimate 32 along with an Asus M2NPV-VM motherboard. After viewing videos on Raid Array setup on Youtube, I decided this chore should not be so difficult. I entered the bios and followed the prompts and made my Raid 1 array. No error messages, and both of my WD3200 HDD were listed, and the array was boot enabled and labeled healthy.
I then inserted my Windows Vista Ultimate CD and clicked on Repair, and on to restore my pc. Windows discovered my external backup, and I then chose the backup that I wanted. I followed the prompts and then clicked restore and received a message that stated that there were to few drives or not enough space to continue. I now do not know how to proceed. Any suggestions would be helpful.
I call this PC my "learning PC". I am trying to learn some of the more exotic functions of my PC. I have read that the Windows Vista built in backup utility is good for backup restore, but not to be used for Raid. Is this true? If so, what product would help me with this issue? Thanks in advance for any suggestions.

Hello. I am new in installing SATA HDD so i am confused when i installed the drive for the first time the nvidia raid bios setup asked me what type am i going to use on the HDD so i selekted the first one that was working (striping). Now my question is: did i selected the proper type ? because i saw that there is other like mirroring and stripe mirroring. If a made a mistake how can i fix it.
 

A:Raid array

It depends what you want to do. Without getting into a discussion about the value of RAID on a home system in general stripe is what you want. Do some reading here. RAID0 is stripe and RAID1 is mirror.

Just make sure you do back ups of your data to another storage source.

Everything seems to be working. Windows XP is seeing it as one drive as i would expect but i want to check it. Is it just a case of unplugging one of the drive and seeing if it still works or is there a more elegant way of testing it?

Oh, and it's just for data. The OS is on a separate drive.

After a power failure, one of my striped drives was not functional in the array anymore. I had to delete the array and redefined it.

I am in need of some advice, and guidance, and maybe some constructive criticism for configuring SSD as a cache for HDD. Now let me begin by giving some specs here:

Intel 40 GB SSD
1TB HDD
Win 7 x64
Intel Rapid Start Technology Utility

So I recently setup this duo in RAID array or at least I think I did. I haven't fiddled with this setup before so I apologize in advance for any "noobiness." Quick summary of what I have done.

Changed SATA mode to RAID in BIOS
Installed OS Win 7 x64
Ran the Intel RST utility

My issue is as follows: When windows restarts I get the Ctrl-I prompt for RAID config. Was i supposed to do some extra configuring here after the fact or just leave it alone? I am under the impression that Intel RST utility tool took care of this. If not what steps do I need to take to finalize my work?

Any and all help appreciated...thanks in advance!

I have run boot & nuke to remove all trace of everything on the drives, unplugged the array and plugged the drives into different sata ports on the motherboard, but BIOS still shows the hard drives as 'Performance' 2tb combined.

Any ideas how I can break the array so BIOS lists as separate drives?

I wouldn't think that was possible. Did you completely disable the RAID functionality in the BIOS? I could see them showing up as inaccessible, until they were formatted.

Hey all,

So I'm running an ASUS M4N72-E mobo which has the Nvidia nForce 750a SLI chipset with built-in SATA RAID. I bought a pair of 1TB Samsung SATA hard drives to set up in a RAID 1 (mirrored) array for backing up pictures and the like, but I can't get the thing to show up in Windows for the life of me...

I first installed the nVidia driver set which supports in-Windows setup and configuration of RAID arrays (Nvidia Mediashield). With that all installed, I shutdown installed the two drives on SATA ports 5&6 which are supposedly for dedicated RAID according to the mobo manual. I went into the BIOS and set onboard SATA to RAID, and went to the RAID configuration utility to make sure both drives were showing up (they are). At first, I didn't set up the RAID in the BIOS config because I was going to do it in Mediashield.

Once I got back into windows the two drives show up as unpartitioned drives in Windows drive manager, and so I load up Nvidia Mediashield go through the steps to set up the array, and when I click "finish" the utility locks up for about 5 minutes (at first I thought formatting the array), but then closes with no messages. Once mediashield closes the drives no longer show up in the device manager or drive partitioner, and no RAID array shows up either. Rebooting is the only way to get them back.

Hi all.

I have a 2 disk RAID1 array in my computer. Was trying to install Windows XP on a seperate drive to dual boot with my existing Vista Ultimate X64 install. I failed at this, but that's another story.

Somewhere during the process something happened with my RAID array (possibly when I unplugged the drives in the array), now my RAID setup says that the array status is "Degraded", and both of the drives in the array show up as seperate drives in Vista.

Any ideas on how this could have happened, and how I can fix it?

The RAID controller is the built in one on my EVGA Nforce 680i SLI motherboard, and I'm using the Nvidia control panel as well as the BIOS RAID settings to try and diagnose and fix the problem.

Thanks in advance for any help, it's really freaking me out that this isn't working right because I store all my work on this array and it'd be disastrous if I were to lose it.

One of your drives is no longer in the array. Unplugging the drive probably caused this, and you need to rebuild the array. See your manual for instructions.

Hi There,

I recently built a new PC. I used an ASUS P5WD Premium mobo, 2 gig or Ram, ASUS ATi PCi Graphics, 2 Maxtor 300 Gig SAT2 H/d's, and Sony DVD-RW & DVD-Rom.
I setup the MAxtor's in Raid 0 (Stripe). My pc failed to boot a couple of times, but went ok after a re-boot, but a few days ago, it had turned itself off. When I re-booted it, I noticed that although the Raid Array is listed as normal and bootable and both H/d's are seen, one is listed as "Error Occurred" and will not boot. After some fiddling it does get to say that Windows cannot boot due to the ...system32\config\system file being missing or corrupt, but if I go to the Repair consol from my XP CD it will do nothing. If I try "CHKDSK" it says it has unrecoverable errors, and it does not appear to be able to access the h/d's in any way such as making directories, or displaying the directory tree!

I have new drives to go in to get me up and running again whilst sending the faulty ones back, but is there a way of getting them up and running to be able to get some files of of them, and/or wiping them before I send them back. Even better, can I repair? I have tried the Maxtor Power Max software but it does not see the h/d's, I guess because they are in a Raid Array??

Any help please??

I noticed something odd...

In an attempt to ensure all files (including boot files) were installed on only my SSD, I disabled all my other HDD's in the BIOS.

Installed Win7 RTM x64, everything worked well. BUT when I re-enabled all the other HDD's...Win7 blue screened before it could load (got half way through the animation, then poof, blue screen)

Wouldn't boot in Safe mode, System restore did nothing...

Reinstalled Win7 with my SSD and RAID array enabled and everythings fine.

Seems Win7 can't handle a RAID array being added after installation, as in it can't find or handle the driver for it when it gets suddenly added.

Anyone have a similar issue? Not looking for a resolution because I have everything running fine now. Just curious if anyone has encountered this or similar.

Win 7 does seem to be finiky when it comes to raid. I found out the hard way not to remove the raid when I recommended a user not have the controller attached when he was installing. It fixed all the other problems with drivers till he installed the reaid controller the BSOD. SO I guess its a balancing act.

I know I can do this if I was using SCSI disks with Compaq's SMART controllers, but I can't find anything that says I can do it with IDE ATA.

SIIG's best only allows raid0, raid1, and raid0+1
Promise is worse: they truncate the larger disks to match the smaller disks.
Adaptec is unclear whether they can or not.

Anyone?
 

A:Can't you do multi-array raid with IDE ATA hdd?

You haven't stated what OS you're running, so I'll assume you have Windows 2000 or XP (you can do this in Linux too, but I haven't tried it). What you can do is make a RAID-0 of the two 80GBs and a RAID-0 of the two 200GBs (using whatever RAID card you get). Then make a 10GB partition on the 2x80 array, and install Windows on that. Then you can just use Windows' built-in software RAID to join the rest of the 2x80 array with the 2x200 array to make a single large JBOD drive. That way all your data is still striped, but you get the 10GB + 550GB configuration you desire.

I'm having a problem with a potentially failing RAID array and/or disk drives.

Two weeks ago, I was burning a DVD from files on the RAID array when the burn failed with a data read error. The array subsequently displayed the following characteristics:

1. Event Viewer showed a 'The device, fasttrack1, did not respond within the timeout period' error, followed by a thousand simultaneous errors that said 'An error was detected on device.. 'harddisk2'.. during a paging operation'.

2. The RAID drive and all directories were viewable in Windows Explorer. No files within those directories could be read or written, however, and switching to thumbnail view would not show thumbs of images of any size.

3. The Disk Manager within Computer Management would not detect the RAID array.

4. After rebooting, the array works as usual. It has again failed during another DVD burning operation just today, and again works after a reboot.

My configuration:

Athlon 2000 / Gigabyte GA-7VAXP (Via) / onboard Promise RAID controller / Win2000

Well, the best advice I can offer is to do a backup of any data on the RAID drives right now!

If you want to test the drives independently, you'll need to use the disk manufacturer's utility and configure the RAID controller to allow the drives to be used in a non-RAID environment. Obviously, this is best done when you have proper backups of what's on the drives!

I had my Raid 5 crap out on me on Sunday and I get an error message when the RAID controller's BIOS boots up. It's a Highpoint 1640 controller and it has driver/BIOS version 2.06s on it. The controller's BIOS screen comes up and lists hard drives 1&3 and then has a little message screen that asks "power off, destroy, continue". If I select "continue" and press enter then a second BIOS screen comes up (same as the first screen) only this time it has hard drive 2 listed and has the same little message screen. Through experimentation I plugged and unplugged various drives in different combinations and think I've determined that the drives 1&3 are the parity drives and drive 2 is the original hard drive that 1&3 have the split data because if any thing other than 1&3 is plugged/unplugged I get the bootscreen screen that ask insert disk/ boot from disk or press F1.

Quote:
Setting up your system to run on a PAIR of very fast SATA hard drives is the first step towards alleviating this problem of massive disk swapping (and its resulting bottlenecks). Those drives should then be configured as a RAID 0 array. Oblivion and your other games should be run entirely from that array. By having a pair of drives operating in tandem, the data can be swapped back and forth at an enormously faster rate and your gameplay will be incredibly improved overall.


Any help would be appreciated. Thanks

A:Help Setting Up RAID 0 Array

Typically with all standard RAID setups, you have an option before Windows is called to take over the booting where you can set up and make changes to your RAID. This is usually either in the BIOS or right after the POST screen before Windows. It's usually pretty quick and involves an F-key to load the settings menu.

I don't have a RAID but as far as I know, you plug in your drives (in pairs or quads, etc etc) and load this settings menu and tell it what you want to create. It should fire away and build the RAID and life is good. Restart, pop in your Windows disk and off you go.

If you are mirroring your data (RAID 1), if one drive fails you are still alive, not gaining much in performance. If you stripe your disks (RAID 0) and create one fatty disk, if one fails, you're not so lucky, unless you do a RAID 5 (RAID 1s full of 0s, SORT OF like a full house in poker), there's more to lose with RAID 1.

HOWEVER, you will see the best performance from a RAID 0 at the cost of potential data loss without a proper backup.

How does this apply when you are cloning from a parallel install.

I am trying to clone a W2k3 Server Domain controller from a smaller to larger raid array. Both arrays are on the same controller, an Adaptec SA2810. I am booting to a parallel install on a sata drive connected to the controller on the motherboard and performing the clone of the smaller array dead to the larger array.

The system completes the clone then reboots back to the parallel install. I then change the settings in bios to change the boot order and reboot and that resolves the problem of booting to the parallel install, but changing the boot order on the raid controller does not result in the larger array being seen as the C Drive when the smaller original array is connected.

I am loathe to disconnect the smaller original array prior to my knowing everything works, because if something goes wrong and I cannot get the original array back on the controller I could be in serious trouble.

I have gone through the cloning procedure twice already so I know it works, I just have to get past the drive assignment issue. Any help would be greatly appreciated.
