  • Backup data from RAID 1 disk out of its server

    - by Doomsday
    I'm facing with a pretty easy problem in my opinion. I've extracted a working disk from a RAID1 and I'm looking to copy only data (FS and RAID configuration doesn't matter) into another location (another FS). My problem is I'm not able to mount properly this disk into another linux. I've first looked the partition table : # fdisk -l /dev/sdc Disk /dev/sdc: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders, total 1250263728 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 63 1249535699 624767818+ fd Linux raid autodetect /dev/sdc2 1249535700 1250017649 240975 fd Linux raid autodetect /dev/sdc3 1250017650 1250258624 120487+ 82 Linux swap / Solaris I've understood I should use dmraid tools.

Anyone has a clue ?

  • Unable to Install GRUB in /dev/sda on raid drives

    - by Henry
    I'm trying to install 12.04LTS on a server but keep running into the unable to install grub error like so "Unable to Install GRUB in /dev/sda". The drives are in raid1 and I'm using fakeraid on a supermicro motherboard, which according to the manual is fully supported. I've tried installing both from USB and CD-R but still no luck. I'm not dual booting with any other OS, just using 2x320gb drives and have been choosing to install using the entire disk. Any ideas what I'm doing wrong or can do to fix this? Thanks

  • Ubuntu 12.04 boot degraded raid

    - by beacon_bonanza
    I've installed Ubuntu 12.04.1 in a new server and set up the 4 hard drives with 3 RAID 1 devices, the configuration is such that the first two drives have md0 (swap space) and md1 (/) with the third and fourth drives having md2 (/var). I've been testing the operation under a drive failure and found that the system boots fine if I remove disk two but if I remove disk one then the system gets to grub and then just restarts. I'm confused as to why grub appears to be loading properly from disk two but then the boot fails. I've tried to copy the MBR from disk 1 to 2: dd if=/dev/sda of=/dev/sdb bs=512 count=1 but this didn't make a difference. Any ideas how to get it to boot from just the second disk? fdisk -l Disk /dev/sda: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000ccfa5 Device Boot Start End Blocks Id System /dev/sda1 2048 31250431 15624192 fd Linux RAID autodetect /dev/sda2 * 31250432 3907028991 1937889280 fd Linux RAID autodetect Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000ccfa5 Device Boot Start End Blocks Id System /dev/sdb1 2048 31250431 15624192 fd Linux RAID autodetect /dev/sdb2 * 31250432 3907028991 1937889280 fd Linux RAID autodetect Disk /dev/sdd: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00035b05 Device Boot Start End Blocks Id System /dev/sdd1 2048 3907028991 1953513472 fd Linux RAID autodetect Disk /dev/sdc: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000c73aa Device Boot Start End Blocks Id System /dev/sdc1 2048 3907028991 1953513472 fd Linux RAID autodetect Disk /dev/md1: 1984.3 GB, 1984264208384 bytes 2 heads, 4 sectors/track, 484439504 cylinders, total 3875516032 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md2: 2000.3 GB, 2000263380992 bytes 2 heads, 4 sectors/track, 488345552 cylinders, total 3906764416 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md0: 16.0 GB, 15990652928 bytes 2 heads, 4 sectors/track, 3903968 cylinders, total 31231744 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000

  • Linux software Raid 10 no superblock

    - by Shoshomiga
    I have a software raid 10 with 6 x 2tb hard drives (raid 1 for /boot), ubuntu 10.04 is the os. I had a raid controller failure that put 2 drives out of sync, crashed the system and initially the os didnt boot up and went into initramfs instead, saying that drives were busy but I eventually managed to bring the raid up by stopping and assembling the drives. The os booted up and said that there were filesystem errors, I chose to ignore because it would remount the fs in read-only mode if there was a problem. Everything seemed to be working fine and the 2 drives started to rebuild, I was sure that it was a sata controller failure because I had dma errors in my log files. The os crashed soon after that with ext errors. Now its not bringing up the raid, it says that there is no superblock on /dev/sda2. I tried to reassemble manually with all the device names but it still would not bring up the raid 10 complaining about the missing superblock on sda2, and sda1 was also dropped from the raid 1. When I did examine on the raid10 it says that 1 of the initially failed drives is a spare, the other is spare rebuilding and sda2 is removed. It seems that sda decided to fail right when the system was vulnerable to it because when I boot up a live cd it spews out sda unrecoverable read failures. I have been trying to fix this all week but I'm not sure where to go with this now, I ordered more hard drives because I didn't have a complete backup, but its too late for that now and the only thing I could do is mirror all the hard drives onto the new ones (I'm not sure whether sda was mirrored without errors). On the internet I read that you can recover from this by recreating the array with the same options as when it was made, however because sda is failing I cant use it and I don't want to risk using its mirror instead, so I'm waiting to get another hard drive. I'm also not sure whether to include the out of sync drives or if I can actually use those instead to recover the array. Sorry if this is a mess to read but I've been trying to fix this all day and its late at night now, any thoughts on this would be greatly appreciated. I also did a memtest and changed the motherboard in addition to everything else.

  • 13.10 - Weird WiFi connection problems - WMP300N - Broadcom BCM4321

    - by user1898041
    Just installed 13.10 on my desktop and I really like it. After having problems with getting the wifi to work, I installed it connected to the internet with an ethernet cable and added in the 3rd party software and updates as per the installation procedure. After installation was completed, I saw the wifi icon in the upper right hand corner, but it was not seeing any wifi networks. Some Googling brought me to use the 'Additional Drivers' application. It found the WMP300N Broadcom BDM4321 based pci wifi card and installed the proprietary Broadcom STA wireless driver, which may have been installed before. I'm not sure. Here is the weird part: when I start my system, wifi seems to be in some sort of suspended state where the system sees that the card exists but the card will not detect any wifi networks. It will work after booting once I 'Additional Drivers' application and then start FireFox. I know it seems weird, but this is the process I've got down to get the card to recognize wifi networks. After those applications are open for a few seconds, the card starts to function like normal (although maintaining the wifi connection is problem but most likely a seperate issue). The reason this is a problem is because this is supposed to just be a headless box managed through SSH. Here are the readouts from the common network diagnosis programs BEFORE I open 'Additional Drivers' and 'FireFox'. All commands were done with sudo. lspci 00:00.0 Host bridge: Intel Corporation 82G35 Express DRAM Controller (rev 03) 00:01.0 PCI bridge: Intel Corporation 82G35 Express PCI Express Root Port (rev 03) 00:1a.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 02) 00:1a.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 02) 00:1a.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 02) 00:1a.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 (rev 02) 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 02) 00:1c.4 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 5 (rev 02) 00:1c.5 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 6 (rev 02) 00:1d.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 02) 00:1d.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 92) 00:1f.0 ISA bridge: Intel Corporation 82801IR (ICH9R) LPC Interface Controller (rev 02) 00:1f.2 SATA controller: Intel Corporation 82801IR/IO/IH (ICH9R/DO/DH) 6 port SATA Controller [AHCI mode] (rev 02) 00:1f.3 SMBus: Intel Corporation 82801I (ICH9 Family) SMBus Controller (rev 02) 01:00.0 VGA compatible controller: NVIDIA Corporation GT216 [GeForce GT 220] (rev a2) 01:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1) 02:00.0 Ethernet controller: Qualcomm Atheros Attansic L1 Gigabit Ethernet (rev b0) 03:00.0 IDE interface: JMicron Technology Corp.

  • Do RAID controllers commonly have SATA drive brand compatibility issues?

    - by Jeff Atwood
    We've struggled with the RAID controller in our database server, a Lenovo ThinkServer RD120. It is a rebranded Adaptec that Lenovo / IBM dubs the ServeRAID 8k. We have patched this ServeRAID 8k up to the very latest and greatest: RAID bios version RAID backplane bios version Windows Server 2008 driver This RAID controller has had multiple critical BIOS updates even in the short 4 month time we've owned it, and the change history is just.. well, scary. We've tried both write-back and write-through strategies on the logical RAID drives. We still get intermittent I/O errors under heavy disk activity. They are not common, but serious when they happen, as they cause SQL Server 2008 I/O timeouts and sometimes failure of SQL connection pools. We were at the end of our rope troubleshooting this problem. Short of hardcore stuff like replacing the entire server, or replacing the RAID hardware, we were getting desperate. When I first got the server, I had a problem where drive bay #6 wasn't recognized. Switching out hard drives to a different brand, strangely, fixed this -- and updating the RAID BIOS (for the first of many times) fixed it permanently, so I was able to use the original "incompatible" drive in bay 6. On a hunch, I began to assume that the Western Digital SATA hard drives I chose were somehow incompatible with the ServeRAID 8k controller. Buying 6 new hard drives was one of the cheaper options on the table, so I went for 6 Hitachi (aka IBM, aka Lenovo) hard drives under the theory that an IBM/Lenovo RAID controller is more likely to work with the drives it's typically sold with. Looks like that hunch paid off -- we've been through three of our heaviest load days (mon,tue,wed) without a single I/O error of any kind. Prior to this we regularly had at least one I/O "event" in this time frame. It sure looks like switching brands of hard drive has fixed our intermittent RAID I/O problems! While I understand that IBM/Lenovo probably tests their RAID controller exclusively with their own brand of hard drives, I'm disturbed that a RAID controller would have such subtle I/O problems with particular brands of hard drives. So my question is, is this sort of SATA drive incompatibility common with RAID controllers? Are there some brands of drives that work better than others, or are "validated" against particular RAID controller? I had sort of assumed that all commodity SATA hard drives were alike and would work reasonably well in any given RAID controller (of sufficient quality).

  • How to install RAID drivers on already installed Windows 7?

    - by happysencha
    64-bit Windows 7 Ultimate 6GB RAM Intel i7 920 Intel X25-M SSD 80GB 2,5" Club 3D Radeon HD5750 GA-EX58-UD4P Motherboard I've been running fine with Windows 7 installed on the SSD. I wanted to create an mirrored Raid-1 setup for backups using two hard disks, so I ordered two Samsung HD203WI. This motherboard supports two different RAID controllers, the Intel's ICH10R and Gigabyte's SATA2 SATA controller. There are 6 SATA ports behind the ICH10R and 2 SATA ports for the Gigabyte controller. I googled around and seemed that the ICH10R is a better choice and since then I've been trying to make it work. When I activate the [RAID] mode from BIOS, the Windows 7 gives BSOD exactly as described by this guy: "Windows 7 will start to boot, it gets to the screen where there are 4 colors coming together and it blue screens and restarts no matter what I do." First thing I did: turned off the RAID and booted to Windows and tried to install the SATA RAID drivers from Gigabyte. I launch the driver installation program and it gives "This computer does not meet the minimum requirements for installing the software" error. I then tried Intel's Rapid Storage Technology drivers (which apparently is the same as the one offered at Gigabyte's site), but it resulted in exactly the same error. I then detached the new Samsung hard disks from the SATA ports, but left the [RAID] enabled in BIOS. To my surprise, it still BSOD'd, so at this point I knew it is an OS/driver issue. Also, I tried with the Gigabyte's RAID enabled (while the ICH10R RAID disabled) and it booted just fine. So then I thought, that maybe I can't install the RAID drivers from within the OS. So I caused the BSOD on purpose once again, and then with ICH10R RAID activated and Samsung hard disks attached, I choose the Windows 7 Recovery mode in the boot menu. It sees some problem(s), tries to repair, does not succeed and does not ask for drivers (which I put on a USB stick) to install. I also tried to use the command-line in the recovery: "rundll32 syssetup, SetupInfObjectInstallAction DefaultInstall 128 iaStor.inf" but it gave "Installation failed." So I'm clueless how should I proceed. Do I really need to re-install Windows 7 and load RAID drivers in the Win7 setup? I don't want to install any OS on the RAID, the Windows 7 is and will be on the SSD. I just want to have a RAID-1 backup using those two hard disks. I mean why would I need to re-install operating system to add RAID setup?

  • Degraded RAID5 and no md superblock on one of remaining drive

    - by ark1214
    This is actually on a QNAP TS-509 NAS. The RAID is basically a Linux RAID. The NAS was configured with RAID 5 with 5 drives (/md0 with /dev/sd[abcde]3). At some point, /dev/sde failed and drive was replaced. While rebuilding (and not completed), the NAS rebooted itself and /dev/sdc dropped out of the array. Now the array can't start because essentially 2 drives have dropped out. I disconnected /dev/sde and hoped that /md0 can resume in degraded mode, but no luck.. Further investigation shows that /dev/sdc3 has no md superblock. The data should be good since the array was unable to assemble after /dev/sdc dropped off. All the searches I done showed how to reassemble the array assuming 1 bad drive. But I think I just need to restore the superblock on /dev/sdc3 and that should bring the array up to a degraded mode which will allow me to backup data and then proceed with rebuilding with adding /dev/sde. Any help would be greatly appreciated. mdstat does not show /dev/md0 # cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] md5 : active raid1 sdd2[2](S) sdc2[3](S) sdb2[1] sda2[0] 530048 blocks [2/2] [UU] md13 : active raid1 sdd4[3] sdc4[2] sdb4[1] sda4[0] 458880 blocks [5/4] [UUUU_] bitmap: 40/57 pages [160KB], 4KB chunk md9 : active raid1 sdd1[3] sdc1[2] sdb1[1] sda1[0] 530048 blocks [5/4] [UUUU_] bitmap: 33/65 pages [132KB], 4KB chunk mdadm show /dev/md0 is still there # mdadm --examine --scan ARRAY /dev/md9 level=raid1 num-devices=5 UUID=271bf0f7:faf1f2c2:967631a4:3c0fa888 ARRAY /dev/md5 level=raid1 num-devices=2 UUID=0d75de26:0759d153:5524b8ea:86a3ee0d spares=2 ARRAY /dev/md0 level=raid5 num-devices=5 UUID=ce3e369b:4ff9ddd2:3639798a:e3889841 ARRAY /dev/md13 level=raid1 num-devices=5 UUID=7384c159:ea48a152:a1cdc8f2:c8d79a9c With /dev/sde removed, here is the mdadm examine output showing sdc3 has no md superblock # mdadm --examine /dev/sda3 /dev/sda3: Magic : a92b4efc Version : 00.90.00 UUID : ce3e369b:4ff9ddd2:3639798a:e3889841 Creation Time : Sat Dec 8 15:01:19 2012 Raid Level : raid5 Used Dev Size : 1463569600 (1395.77 GiB 1498.70 GB) Array Size : 5854278400 (5583.08 GiB 5994.78 GB) Raid Devices : 5 Total Devices : 4 Preferred Minor : 0 Update Time : Sat Dec 8 15:06:17 2012 State : active Active Devices : 4 Working Devices : 4 Failed Devices : 1 Spare Devices : 0 Checksum : d9e9ff0e - correct Events : 0.394 Layout : left-symmetric Chunk Size : 64K Number Major Minor RaidDevice State this 0 8 3 0 active sync /dev/sda3 0 0 8 3 0 active sync /dev/sda3 1 1 8 19 1 active sync /dev/sdb3 2 2 8 35 2 active sync /dev/sdc3 3 3 8 51 3 active sync /dev/sdd3 4 4 0 0 4 faulty removed [~] # mdadm --examine /dev/sdb3 /dev/sdb3: Magic : a92b4efc Version : 00.90.00 UUID : ce3e369b:4ff9ddd2:3639798a:e3889841 Creation Time : Sat Dec 8 15:01:19 2012 Raid Level : raid5 Used Dev Size : 1463569600 (1395.77 GiB 1498.70 GB) Array Size : 5854278400 (5583.08 GiB 5994.78 GB) Raid Devices : 5 Total Devices : 4 Preferred Minor : 0 Update Time : Sat Dec 8 15:06:17 2012 State : active Active Devices : 4 Working Devices : 4 Failed Devices : 1 Spare Devices : 0 Checksum : d9e9ff20 - correct Events : 0.394 Layout : left-symmetric Chunk Size : 64K Number Major Minor RaidDevice State this 1 8 19 1 active sync /dev/sdb3 0 0 8 3 0 active sync /dev/sda3 1 1 8 19 1 active sync /dev/sdb3 2 2 8 35 2 active sync /dev/sdc3 3 3 8 51 3 active sync /dev/sdd3 4 4 0 0 4 faulty removed [~] # mdadm --examine /dev/sdc3 mdadm: No md superblock detected on /dev/sdc3.

  • 3Ware 9650SE RAID-6, two degraded drives, one ECC, rebuild stuck

    - by cswingle
    This morning I came in the office to discover that two of the drives on a RAID-6, 3ware 9650SE controller were marked as degraded and it was rebuilding the array. After getting to about 4%, it got ECC errors on a third drive (this may have happened when I attempted to access the filesystem on this RAID and got I/O errors from the controller). Now I'm in this state: > /c2/u1 show Unit UnitType Status %RCmpl %V/I/M Port Stripe Size(GB) ------------------------------------------------------------------------ u1 RAID-6 REBUILDING 4%(A) - - 64K 7450.5 u1-0 DISK OK - - p5 - 931.312 u1-1 DISK OK - - p2 - 931.312 u1-2 DISK OK - - p1 - 931.312 u1-3 DISK OK - - p4 - 931.312 u1-4 DISK OK - - p11 - 931.312 u1-5 DISK DEGRADED - - p6 - 931.312 u1-6 DISK OK - - p7 - 931.312 u1-7 DISK DEGRADED - - p3 - 931.312 u1-8 DISK WARNING - - p9 - 931.312 u1-9 DISK OK - - p10 - 931.312 u1/v0 Volume - - - - - 7450.5 Examining the SMART data on the three drives in question, the two that are DEGRADED are in good shape (PASSED without any Current_Pending_Sector or Offline_Uncorrectable errors), but the drive listed as WARNING has 24 uncorrectable sectors. And, the "rebuild" has been stuck at 4% for ten hours now. So: How do I get it to start actually rebuilding? This particular controller doesn't appear to support /c2/u1 resume rebuild, and the only rebuild command that appears to be an option is one that wants to know what disk to add (/c2/u1 start rebuild disk=<p:-p...> [ignoreECC] according to the help). I have two hot spares in the server, and I'm happy to engage them, but I don't understand what it would do with that information in the current state it's in. Can I pull out the drive that is demonstrably failing (the WARNING drive), when I have two DEGRADED drives in a RAID-6? It seems to me that the best scenario would be for me to pull the WARNING drive and tell it to use one of my hot spares in the rebuild. But won't I kill the thing by pulling a "good" drive in a RAID-6 with two DEGRADED drives? Finally, I've seen reference in other posts to a bad bug in this controller that causes good drives to be marked as bad and that upgrading the firmware may help. Is flashing the firmware a risky operation given the situation? Is it likely to help or hurt wrt the rebuilding-but-stuck-at-4% RAID? Am I experiencing this bug in action? Advice outside the spiritual would be much appreciated. Thanks.

After booting into the install wizard and next-ed a few times, On the disk step, it only shows physical harddrive but not the RAID (RAID-10) volume that I set up on the Dell RAID. Is there a special option that I have to set on the boot? or do I need a special driver for this? Please Advise Thanks

  • RAID options for a LAMP web server

    - by jetboy
    I'm due to set up a LAMP web server with four drives and a RAID controller to act as a web server. The drives are 146Gb SAS, and the machine has two quad core processors and 16Gb RAM. There will be very few write operations to the MySQL database, and I'll be using as much caching as possible to reduce disk I/O. Question is: Would I be better off splitting the drives into two RAID 1 arrays, splitting up sequential and random disk I/O, or would I get better overall performance putting them all in a single RAID 1+0 array?

  • Windows 7 won't boot from raid-1 disks until secondary non-bootable disks are removed

    - by PaulP
    I have an ASUS X58 motherboard with a Intel ICH10R southbridge raid controller. Bootable raid-1 SATA disks are on channels 4, 5. Secondary raid-1 SATA disks are on channels 0,1. Everything was working OK until one time I removed the secondary disks and booted successfully but after I shut down and reinstalled the secondary disks rebooting fails with a "Please insert proper boot item" error. If I remove the secondary disks and reboot then do a hot-install of the disks after booting completes, then all is OK. Do I have a raid setup problem or is it something I can fix with Disk Manager.

  • Which is faster? 4x10k SAS Drives in RAID 10 or 3x15k SAS Drives in RAID 5?

    - by Jenkz
    I am reviewing quote for a server upgrade. (RHEL). The server will have both Apache and MySQL on it, but the reason for upgrade is to increase DB performance. CPU has been upgraded massively, but I know that disk speed is also a factor. So RAID 10 is faster performance than RAID 5, but how much difference does the drive speed make? (The 15k discs in the RAID 5 config is at the top of my budget btw, hence not considdering 4x15k discs in RAID 10, which I assume would be the optimum.)

  • Resizing RAID 1 Array on Dell PowerEdge with Perc 4/Di & Windows SBS 2003

    - by Scott McKinney
    I have a Dell PowerEdge 2600 with Perc 4/Di RAID card and Windows SBS 2003 installed. The original system drive was a set of 17GB drives in a RAID 1 array. Over the years, these drives have failed (individually) and been replaced by a set of 73GB drives, but the RAID array is still 17GB in size. Is there a safe procedure to resize the RAID 1 array to use the entire 73GB without destroying/corrupting the data on the array? The Perc documentation mentions a Reconstruct option with Online Capacity Expansion, but is a woefully short on the exact details. Has anyone performed this procedure successfully (or unsuccessfully)? What were the steps? Are there any gotchas I should watch out for?

  • Disabling RAID feature on HP Smart Array P400

    - by Arie K
    I'm planning to use ZFS on my system (HP ML370 G5, Smart Array P400, 8 SAS disk). I want ZFS to manage all disks individually, so it can utilize better scheduling (i.e. I want to use software RAID feature in ZFS). The problem is, I can't find a way to disable RAID feature on the RAID controller. Right now, the controller aggregates all of the disks into one big RAID-5 volume. So ZFS can't see individual disk. Is there any way to acomplish this setup?

  • ML 350 additional SATA RAID controller (mirror only)

    - by Nicholas
    I have a Proliant ML350 G8 with two SAS raid arrays currently set up - thereby maxing the default P420i raid controller. I need to set up a large video dump space in addition to this existing set-up (for non backed up, non-critical, temporary storage). I had planned to just add a 2TB SATA disk and plug it into the motherboard. However I it occurred to me the motherboard might have built-in mirror RAID support? Therefore I could use two SATA disks and have some semblance of redundancy. Is this possible? Or would I need to get a cheap raid card? Any recommendations?

  • Steps to install Windows 7 64bit on RAID 0 (striping)?

    - by marco.ragogna
    I will receive in some days 2x500 GB hard disks (ST3500418AS) and an ASRock 890GX Extreme 3. My idea is to install onto it Windows 7 64-bit in RAID0 configuration (striping). I wondering which steps should I follow, due to the fact I never did it before. Should I install Windows 7 on a single disk and apply the RAID0 later, or should I perform some step through BIOS first and install then Windows 7? If you can, please list me all necessary steps I should follow. Thank you in advance, Marco

    disks 0 and 1 are raid redundant (OS) and the remaining 6 drives are in raid 5 I believe. i would like to pull out disks 0 and 1 and install new drives to build a new OS. I need to be able to reinsert the old drives and reboot back to the original OS. (swap) I had a serious problem in the past attempting this. does the raid require (look for) the drives based on a serial number or something? just dont want to lose data. thanks

Now I need to mount /dev/sda1 and make changes to the grub file, however those changed need to be reflected on the second disk aswell. How do I mount these RAID disks? I can mount one using mount -t ext3however it will damage the RAID array.

  • RAID - software vs. hardware

    - by Robert MacLean
    I have always used hardware based raid because it (IMHO) it's on the right level (feel free to dispute this) and that OS failures are more common to me than hardware issues. Thus if the OS fails the raid is gone and so is the data, where on a hardware level regardless of OS the data remains. However on a recent Stack Overflow podcast they stated they would not used hardware raid as the software raid is better developed and thus runs better. So my question is, is there any reasons to choose one over the other?
