Hardware :: How To Check RAID Status
Jul 15, 2009We have a Dell Poweredge 1750 server with 2 harddrives in RAID 1 running Debian Etch. Yesterday one of the hardrives stopped working but no error message appeared in syslog. The only indication was the amber LED diode. Is there a software way how to check that both disks are OK?

Fedora :: Weekly Raid-check Never Checks Md1?
Feb 21, 2011I have three raid volumes, md0, md1, and md2. The weekly raid-check cron always causes md0 and md2 to get checked but never md1.
/etc/cron.weekly/99-raid-check
Volumes md0 and md1 are on the same 8 disks. Volume md0 is a small raid1 across all 8 disks for boot and md1 is a raid5 that occupies the rest of those 8 disks. Volume md2 is a raid5 on a separate set of 6 drives. When I check /var/log/messages* I see that every Sunday md0 and md2 get checked but md1 is never checked. However, when I run 99-raid-check manually, all three volumes get checked. There is clearly something different between how crond runs that script and how I run it, but I can't imagine what that would be.

I set up the system to send me an email every time the mdadm stat file changed, so it would send me emails when in periodically ran a self-test. I was away and noticed that the self-test was going incredibly slow (usually took 8 hours...was on course for taking 250 days!)

Software :: Rebuilt RAID Array With Old Mount Points Present - File System Check Fails On Boot
Dec 2, 2009I have one hard disk for my root partition and a disk array on a separate mount point. I rebuilt my disk array, but I didn't delete my original mount points beforehand because I was hoping it would just "pick up". So now when I boot up, the OS tells me that the filesytem check fails because it can't find the array to map to the mount point. I know that I need to edit my /etc/fstab and remove the line that defines my mount point on the disk array. But it appears to be read only filesystem when I am in repair mode. I can't force the write with vi.

Feb 1, 2011Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:

/dev/sdb2:

Feb 3, 2010I am new to Debian but not Linux-based systems. I have been experimenting a lot with Debian Lenny/Squeeze. I am growing more comfortable each day with the Debian design. Yet there remain many unexplored areas. I am creating a migration check list. Things to check, prepare, or reconfigure when moving from one Linux-based system to Debian.
I have a good computer background and my current check list probably is fairly good. Yet I would appreciate input and opinions from experienced Debian users of things to watch in such a migration. Login defs, passwd/group files, different directory locations, keymaps, services and daemons, etc. I am not too concerned with the desktop as I plan to stick with KDE 3.5 for a while and I can basically move those settings across.

View 1 Replies View RelatedUbuntu :: Mdadm Raid + GRUB = Not Booting - Error: Unsupported RAID Version: 0.91
Jul 18, 2011I have a raid5 on 10 disk, 750gb and it have worked fine with grub for a long time with ubuntu 10.04 lts. A couple of days ago I added a disk to the raid, growd it and then resized it.. BUT, I started the resize-process on a terminal on another computer, and after some time my girlfriend powered down that computer!
So the resize process cancelled in the middle and i couldn't acess any of the HDDs so I rebooted the server.
Now the problem, the system is not booting up, simple black with a blinking line. Used a rescue CD to boot it up, finised the resize-process and the raid seems to be working fine so I tried to boot normal again. Same problem. Rescue cd, updated grub, got several errors: error: unsupported RAID version: 0.91. I have tried to purge grub, grub-pc, grub commmon, removed /boot/grub and installed grub again. Same problem.
I have tried to erased mbr (# dd if=/dev/null of=/dev/sdX bs=446 count=1) on sda (ide disk, system), sdb (sata, new raid disk). Same problem. Removed and reinstalled ubuntu 11.04 and is now getting error: no such device: (hdd id). Again tried to reinstall grub on both sda and sdb, no luck. update-grub is still generating error about raid id 0.91 and is back on a blinking line on normal boot. When you'r resizeing a raid MDADM changed the ID from 0.90 to 0.91 to prevent something that happend happened. But since I have completed the resize-process MDADM have indeed changed the ID back to 0.90 on all disks.
I have also tried to follow a howto on a similar problem with a patch on [URL] But I cant compile, various error about dpkg. So my problem is, I cant get grub to work. It just gives me a blinking line and unsupported RAID version: 0.91.

Aug 3, 2010I am trying to connect a RAID Box to the server via LSI 8880EM2 RAID controller.The raid box is FUjitsu Externus DX60 with raid 1 configured.The server is Fujitsu Primergy SX300 S5 with LSI 8880EM2 RAID card.The external raid box is being recognised by the raid controllers bios.
The server runs CentOS 5.5 64bit. I have installed the megaraid_sas driver from LSI website and MegaCLI utility but CentOS still fails to see the box.MegaCLI utility, when launched from CentOS, recognises the raid box, CentOS does not(no mapping being created in /dev).
I have also tried to create a logical RAID0 HDD on one physical HDD(as seen by MegaCLI) with MegaCLI utility in CentOS.The result was success and the new logical drive could have been used, but when restarting the server, the controllers' bios fails with an error (not surprised(one logical RAID0 on one physical HDD)) and configuration is being erased.
Has anyone tried connecting 8880EM2 controller to a raid box with raid configured on the box, running it all under CentOS and what were the results.
Ubuntu Installation :: Dual Boot - Win 7 And 10.10 On Raid 0 - No Raid Detect
Nov 26, 2010I have installed Ubuntu on my m1530 since 8.04 and currently dual boot Win7 and 10.10. I would like to dual boot on my PC, but I have run into a problem. I am not a pro at Ubuntu, but this problem I can not solve by reading forums like I have in the past.
I realize this is a common problem, but I have noticed people having success.
I have a M4A87TD EVO MB with two Seagate drives in Raid 0. (The raid controller is a SB850 on that MB) I use the raid utility to create the raid drive that Windows7x64 uses. I have 2 partitions and 1 unused space. Partition 1 is Windows, partition 2 is for media, and the remaining unused space is for Ubuntu.
I am running ubuntu-10.10-desktop-amd64 off a Cruzer 16GB flash drive that was installed via Universal-USB-Installer-1.8.1.4.
My problem like so many others is that when I load into Ubuntu, gparted detects two separate hard drives instead of the raid. I read that this is because kpartx is not installed on 10.10. I then went in LiveCD mode and downloaded kpartx from Synaptic Manager. Gparted still reported two drives. I opened terminal and run a few commands with kpartx. I received an error. (Forgive me I didn't write it down, but I believe it said something about a communication error. I will try again later and see.)
Currently I am reflashing the Cruzer with a persistence of 4GB. I am not familiar with this process, but I understand that my LiveCD boot will save information I download to it. I decided to try this method because I was going to install kpartx and reboot to see if this made a difference.
I am looking for any suggestions on a different method or perhaps someone to tell me that the raid controller or some hardware isn't supported. I did install ubuntu-10.10-alternate-amd64 on my flash drive, but fail to get past detecting my CD-ROM drive since it's not plugged in. If this method is viable, I will plug it in. I also watched the ..... video were a guy creates Raid 0 with the alternated CD, but it wasn't a dual boot and didn't use a raid controller from a MB.

View 1 Replies View RelatedCentOS 5 Hardware :: RAID Or Non-raid HBA Recommendation?
Dec 10, 2009I am going to be using CentOs 5.4 for a home storage server. It will be RAID6 on 6 x 1TB drives. I plan on using an external enclosure which is connected via two SFF-8088 cables (4 drives a piece). I am looking to try and find a non-RAID HBA which would support this external enclosure and allow to use standard linux software raid.
If this is not an option, I'd consider using a hardware based raid card, but they are very expensive. The Adaptec 5085 is one option but is almost $800. If that is what I need for this thing to be solid then that is fine, I will spend the money but I am thinking that software raid may be the way to go.
Ubuntu Installation :: Dual Boot SSD Non Raid - 1 Terabyte Raid 1 Storage "No Block Device Found"?
Sep 15, 2010It's been a real battle, but I am getting close.I won't go into all the details of the fight that I have had, but I've almost made it to the finish line. Here is the set up. ASUS Z8PE-D18 mother board 2 CPU, 8 Gig Ram. I recently added an OCZ Agility SSD, defined a raid 1 virtual disk on the 1 terabyte WD HDD drives, which will holds all of my user data, the SSD is for executables.The bios is set to AHCI. Windows 7 installed fine, recognizes the raid VD just fine.
I installed Ubuntu 10.04 by first booting into try and mode, then opening a terminal and issuing a "sudo dmraid -ay" command. Then performing the install. I told it to install the raid components, and told it to let me specify the partitions manually. When setting up the partitions, I told it to use the free space I set aside on the SSD from the Windows 7 install as ext4 and to mount root there. Ubuntu installed just fine, grub2 comes up just fine, and Windows 7 boots with out a hitch, recognizing the mirrored partition as I indicated previously. When I tell grub to boot linux however, it pauses and I get the "no block devices found" message. It will then boot, but it does not recognize the raid array. After Ubuntu starts up I can run "dmraid -ay" and it recognizes the raid array, but shows the two component disks of the raid array as well. It will not allow the component disks to be mounted, but they show up which is annoying. (I can live with that if I have to)
I have fixed a similar problem before by setting up a dmraid script in /etc/initramfs-tools/scripts/local-top ... following the instructions found at the bottom of this blog:[URL].. To recap: My problem is that after grub2 fires up Ubuntu 10.04.1 LTS (Lucid Lynx), it pauses, and I get "no block devices found" It then boots but does not recognize the raid array untill I manually run "dmraid -ay". I've hunted around for what to do but I have not found anything. It may be some timing issue or something, but I am so tired of beating my head against this wall.
