CentOS 5 Hardware :: Connect A RAID Box To The Server Via LSI 8880EM2 RAID Controller
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.
CentOS 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.
CentOS 5 Hardware :: SW RAID - Raid Devices Larger Than Total Devices
Dec 7, 2010I'm working on a server and noticed that the to RAID5 setup is showing 4 Raid devices but only 3 Total devices. It's on a fully updated CentOS 5 system that only has three SATA drives, as it can not hold anymore. I've done some researching but am unable to remove the fourth device, which is listed as removed. The full output of `mdadm -D /dev/md2` can be see below. I've never run into this situation before.Anyone have any pointers on how I can reduced the Raid Devices from 4 to 3? I have tried
mdadm /dev/md2 -r failed
mdadm /dev/md2 -r detached
but neither work and since there is no block device listed I'm not quite sure how to get things back in sync so it's only seeing the three drives.

CentOS 5 Hardware :: Error Installing CentOS 5.2 On ICH7R With 4 SATA HDDs RAID 5?

Jan 13, 2010My problem is that I'm trying to install CentOS 5.4 x86_64 DVD ISO on Supermicro X7SBI server with installed Adaptec RAID 3405 controller.
I created RAID 5 array and is working fine (adaptec status says Optimal) but I can't install CentOS to that array (1.5TB size).
Whenever I try to install with: linux dd
I'm asked for a driver, which I have downloaded from Adaptec site and extracted contents to USB drive (in installation found as /sba1) which has now a lot of IMG and some ISO files on it.
I try to load (I simplified names) RHEL5.img, CENTOS.img... with x64 names (one exact name: aacraid driverdisk-CentOS-x86_64.img) and I always get the error message: "No devices of the appropriate type were found on this driver disk"
This is going on for a week now and I can't find the right driver or something I'm doing wrong to get install done.
CentOS 5 Hardware :: Installing Centos 5 On HP DL380R05 E5420 With RAID-1?
May 7, 2009I need your help urgently. I will shortly install Centos 5 on a HP DL380R05 E5420 Server with two HP 146GB 10k 2.5 SAS HP SP hard disks running hardware RAID-1. I am a newbie on CentOS, please advise me:
1. Do I need a Centos RAID device driver for hardware RAID-1 on the HP DL380R05 E5420 Server?
2. Should I use Centos i386 or Centos x86_64 in this case? Which one: CentOS 5.2 or CentOS 5.3?
3. Does Centos support Embedded NC373i Multifunction Gigabit network cards?

CentOS 5 Hardware :: Intel S5000Vsa And RAID Driver With Centos 5.4?
Dec 31, 2009I've a Centos 5.1 server on S5000vsa Intel board with 6 bay HD in raid 1 mode (2 HD), and working fine until I've decide to make a yum update. Today the Centos is 5.4 but seems necesssary to upgrade the megasr driver for the raid function (i.e. , is not possible to contact the raid firmware trought Web Console 2). I've download the last megasr driver from Intel and I follow the instruction to upgrade the driver with s.o. installed, but when I start the server and choose via grub the new img boot file, the display show :
megasr.ko invalid module format -1 and stop. The linux version is the same in the machine (uname -a) and from the driver (2.6.18-164.9.1.el5). Another question : in Intel instruction spoken about megasr.o , but on img file I found a megasr.ko . I think instructions referre to old linux 2.4

Ubuntu :: Software Raid Does Not Mount On Startup?
Jul 18, 2010I am running 64bit ubuntu 10.04. I have an nvidia software raid formatted with ntfs. The raid only mounts about every 10-15 boots. It is completely random on when it will mount. I even have included "force" in the ntfs-3g mount options.
Also, possibly related, many times ubuntu will not even load unless I load windows first and then restart. I run Ubuntu on its own partition using ext3, so this makes no sense.... It makes me scared to run a computer with only Ubuntu because it seems Ubuntu cannot load unless window loads before it! I could understand this if Ubuntu was formatted as NTFS, but the only NTFS drive Ubuntu sees is the raid, which is not mounting anyways, so why is it dropping to the command prompt?

General :: RAID Impossible To Mount Through Fstab
Nov 3, 2010After having solved my raid5 creation problems, I'm running into a new one: the RAID is just impossible to mount through fstab. I get a wonderful "The disk drive for /dev/md0 is not ready yet or not present.

Once the system has booted, I can perfectly run a mount /dev/md0 /media/raid and mount it manually.

Ubuntu :: RAID Configuration - HD Crashes (No Mount Point)
Mar 17, 2010We have 4 HDs on our server. One of them broke last night. I could see a message on the server and after restarting the S.M.A.R.T. on the BIOS was recognizing one HD as bad. After removing the failing HD, the server is now up and running. I do not remember how I configured the HDs. During the installation I had a few problems and I change a few times what I wanted to do. I am sure I had at least a RAID0 with 2 disks but I could have put all the 4 disk in the RAID having 2 disks as spare drives or I may have created another volume for the other 2....

2-How can I find what was on the disk that died? (Was it a spare drive or one of the 2 in mirror)?
3-What do I need to do now to be sure that the mirroring is working OK? (considering that there is a spare drive). Do I need to use a command to let ubuntu mirror the drive on the new one?
4-What do I need to do when I get a replacement of the broken disk?

Ubuntu Servers :: Cannot Mount Existing Jmicron Raid 1
May 28, 2010I have recently had a problem with my 10.04 server machine. It will not boot, it seems to be taking forever on the loading screen (normally headless server, but I connected monitor when I couldn't ssh), but that's not why I'm here.
Knowing that I do rsync backups every night at midnight of my machine I just bit the bullet and formatted my / partition. Reinstall went fine, I turned off automatic updates (I suspect an update caused the problem) But now I cannot mount my jmicron raid 1, which is where my rsync backup is (doh!).

View 5 Replies View RelatedUbuntu :: Raid Array Won't Mount Since Rebuilding - Bad Geometry?
Jun 15, 2010I had run out of space on a 30GB raid1 partition so I rebuilt it as I had three 30GB partitions on a pair of 120GB drives. I stopped the array and used gparted to create a single 120GB partition on one of the disks. I then copied the data from all three partitions on the other drive onto this newly cleared space, before zapping that too. So I now had two drives with identical single partitions, one of which had all my data and lots of space. I used mdadm to create a new array from the two disks, which looked good. It immediately started to resync the data onto the second drive. However, when I tried to mount the new array this is what I get:
Code:
bob@zaphod:~$ sudo mount -t ext4 /dev/md0 /media/raid/
mount: wrong fs type, bad option, bad superblock on /dev/md0,
missing codepage or helper program, or other error
[code]....
I can mount the drives independently and GOOD NEWS the data is there! However, how can I get round this problem and mount the raid array.
Server :: Directly Mount Raid Array Member?
Apr 8, 2010Is there a way for me to mount a raid array member directly without using any of the raid tools? For instance, I have a raid 1 array that contains /dev/sda1 and /dev/sdb1. How can I mount /dev/sda1 or /dev/sdb1 directly? Doing mount /dev/sda1 <mnt point> does not work. If I try specifying the filesystem type with -t this doesn't work either.
View 1 Replies View RelatedServer :: Mount Raid Device To Recover Data?
Aug 20, 2009In a nutshell, our RAID 1 array was rendered broken and we were advised that core lib files were missing and the OS needed to be reloaded... a quote from our server host:"The OS is not healthy.This server will need a reinstall.
Libs are missing." This was after having replaced what we though was a faulty /dev/sdb. So they reloaded the OS (Debian 5.0.2 x86_64) on 2 FRESH drives, and installed the old /dev/sda as /dev/sdc once the reload was completed. Here's the output of /etc/fstab on the fresh install so we know what we're working with:
Code:
debian:/BAK# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
[code]....
The one problem I see myself running into is /dev/md1 and /dev/md2 are currently in use by the new system, so I cannot mount it there. I should also note, reloading the OS is a viable option if needed as we haven't started configuring the server yet. So if we need to reinstall the OS and assign the NEW RAID arrays to something other than /dev/md1 and /dev/md2 then we can do that.
CentOS 5 :: Mount Error: Can't Mount An Encrypted Volume With An Overlaying Ext3 FS
Jun 6, 2010I created a encrypted volume on top of software raid1. These are my steps:
1. Create logical partition on sda
2. Create logical partition on sdb (same size)
3. Change type to partition to 'fd' for both partitions
4. Check that the both partitions are same size and type fdisk -l /dev/sda && fdisk -l /dev/sdb
5. partprobe
6. Make sure there are no remains from previous RAID installations on /dev/sdb by running: mdadm --zero-superblock /dev/sda6 mdadm --zero-superblock /dev/sdb6
7. mdadm --create /dev/md4 --level=1 --raid-disks=2 /dev/sda6 /dev/sdb6
8. watch cat /proc/mdstat
9. update mdadm.conf mdadm --examine --scan | grep mdx >> /etc/mdadm.conf
10. Load twofish module [root@localhost ~]# modprobe twofish
11. # cryptsetup -y -c twofish-cbc-essiv:sha256 create ftdata /dev/md4 Enter passphrase: Verify passphrase:
12. mkfs.ext3 -b 4096 -R stride=8 /dev/mapper/ftdata
13. mkdir /ftdata
14. Mount the encrypted volume:
mount -O noatime /dev/mapper/ftdata /ftdata
It mounts successfully this first time. When I cd /ftdata, I can see the lost+found dir
[Code]....
So why is it that I can't mount my encrypted volume after the first time? I am giving the correct password when it asks to.
Ubuntu Servers :: RAID-5 Recovery (spare/active) / Degraded And Can't Create Raid ,auto Stop Raid [md1]?
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:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00

Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.
CentOS 5 Hardware :: How To Install CentOS On RAID 5.I
May 10, 2011I have DELL R310 server with PERC 200H controller and RAID 5 configured already.This is my first time I want to install CentOS and seems like a new challenge for me I've read some articles on Wiki and posts on this forum and didn't find any information how to install CentOS on RAID 5.I only noticed that if there is fake or software RAID1 it should be switched off and made by OS configuration.I think PERC 200H is separate controller so RAID 5 is hardware RAID, is there anybody who can confirm ?My problem is that when I try to install CentOS it doesn't see any hard disks ... I looked for drivers on DELL web site and there is driver for Red Hat 6. I tried to install it using linux dd command but it doesn't recognize. Is there anybody else who met such problem ?

View 4 Replies View RelatedDebian :: Reverting RAID 1 - Mount Partition As Standalone Encrypted Disk
Feb 11, 2011I have 2 identical disks originally configured as a pair for a server. Each of the disks has 2 partitions dev/sdb1,dev/sdb2. The sdb1 partitions I had configured as a raid1 mirror. The sdb2 partitions were non-raid and used as extra misc. Space. Further, the raid setup is also encrypted using dm-crypt luks. Now I want to redeploy each of the disks for new purposes. One of the disks i want to deploy exactly as before (keeping the partitions and content), however without being part of a raid array.
I've successfully deployed this disk into a new system and I am mounting the dev/sdb1 partition as dev/md0 because the disk is set to autodetect raid. Actually I am using cryptsetup and mounting with mapper. Can I get rid of the setting for auto detect on this partition without losing the data, or breaking the encryption? I just want to mount the partition as a standalone encrypted disk. Is it as simple as doing crypt setup luksOpen /dev/sdb1 then mounting it with mapper? Or do I need to change the partition in some way. Or do I simply continue to operate it as a 'broken' raid array?
Server :: Unable To Mount Additional Harddrive From RAID Volume System
Apr 8, 2010I believe server section is the best when speaking of RAID stuff...
I have the following situation:We have a DELL T3400 with embedded fake raid on it. I dont know exactly how the system was setup (I wasnt here at that time), but the RAID was enabled in bios and while booting, the two harddrives would be seen as members of intel raid volume0 (RAID 1 mirror). I am not sure if the software raid was actually properly configured in Linux (Fedora 9) and if the OS was reconstructing the whole raid or it was just the bios part that was mirroring the /boot or just some parts of it. Frankly I find these hydrid raids very confusing.Some bad disk manipulation from my part caused the server to crash, but I was able to recover and boot just with one hard drive after using fsck.
I decided to get rid of the raid as it's not the right solution for the application we need it for and decided to go for a traditional single harddrive system and to use Ghost for Linux to clone to a spare disk when backups are needed.So I installed the latest Fedora 12 distribution onto another harddrive and disabled RAID in bios (changed from RAID ON to autodetect, which is the only other option).
Here is what I have now:
/dev/sda has the newly installed fedora 12
/dev/sdb is an empty harddrive that I would use as an intermediate
/dev/sdc is the old harddrive member of intel raid volume0
sdb was partitioned into sdb1 sdb2 and sdb3 and I created an ext3 filesystem on sdb2. The hard drive belonging to RAID volume0 (sdc) has a lot of work done on it and I would like to be able to recuperate the files to the new disk (sda). I cannot mount that old harddrive while in fedora 12, as it sees some unknown raid member filesystem on it probably assigned by the intel raid chip.
So I decided to do it from the other side: to boot from raid volume 0, and from there mount a third intermediate harddrive (sdb) onto which I would copy the documents and then mount the same harddrive from the newly installed fedora 12 and copy those documents from that intermediate harddrive.I can mount /dev/sdb2 from fedora 12 fine and copy stuff to and from it, but not when I boot from the RAID volume 0 harddrive (sdc) with fedora 9 on it. It keeps saying that the partition in question (/dev/sdb2) is an invalid block device.I am stuck here, as my knowledge in this sort of things is very limited.If somebody can indicate me how to recuperate files from that old raid harddrive onto the new fedora 12 drive, I would appreciate a lot.
