Just had my Raid 5 config on Sme server 7.4 crash due to a faulty drive, I have manage to setup a machine with ubuntu 9.04 and installed the drives in there original config (I haven't overwritten them). Ubuntu can see the raid config but for some reason I cannot mount it as it keeps asking for the filesystem which if I check says LVM2_member, anyone know how I could get it to mount?

View 1 Replies View RelatedI 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.

I worked around this problem by reverting to the previous kernel 2.6.32.9-70. From what I can tell, with the newer kernel there is a problem with device enumeration of software raid volumes.

I just had a whole 2TB Software RAID 5 blow up on me. I rebooted my server, which i hardly ever do and low and behold i loose one of my raid 5 sets. It seems like two of the disks are not showing up properly.. What i mean by that is the OS picks up the disks, but it doesnt see the partitions.
I ran smartct -l on all the drives in question and they're all in good working order.
Is there some sort of repair tool i can use to scan the busted drives (since they're available) to fix any possible errors that might be present.
Here is what the "good" drive looks like when i use sfdisk:

I have a home server running Openfiler 2.3 x64 with 4x1.5TB software RAID 5 array (more details on the hardware and OS later). All was working well for two years until several weeks ago, the array failed with two faulty disks at the same time. Well, those thing could happen, especially if one is using desktop-grade disks instead of enterprise-grade ones (way too expensive for a home server). Since is was most likely a false positive, I've reassembled the array:
Code:
# mdadm --assemble --force /dev/md0 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1
mdadm: forcing event count in /dev/sdb1(0) from 110 upto 122
mdadm: forcing event count in /dev/sdc1(1) from 110 upto 122
[code]....
Right. Once is just a coincident but twice in such a sort period of time means that something is wrong. I've reassembled the array and again, all the files were intact. But now was the time to think seriously about backing up my array, so I've ordered a 2TB external disk and in the meantime kept the server off. When I got the external drive, I hooked it up to my Windows desktop, turned on the server and started copying the files. After about 10 minutes two drives failed again. I've reassembled, rebooted and started copying again, but after a few MBs, the copy process reported a problem - the files were unavailable. A few retried and the process resumed, but a few MBs later it had to stop again, for the same reason. Several more stops like those and two disks failed again. Looking at the /var/log/messages file, I found a lot of error like these:

I am looking to convert a raid 1 server I have to raid 10. It is using software raid, currently I have 3 drives in raid 1. Is it possible to boot into centos rescue, stop the raid 1 array. Then create the raid 10 with 4 drives, 3 of which still has the raid 1 metadata, will mdadm be able to figure it out and resync properly keeping my data? or is there a better way to do it?

Can I some how add the second drive and get the box to mirror from here own out? The box gets really hot and I want to be ready for a HD failure.

I recognize that this isn't the typical question, but I have a problem with my OpenSUSE webserver, and I thought I would prevail on the community for some guidance. I have this webserver with an important MySQL db on it. The RAID array seems to have died while I was moving. (did someone drop it? dunno) Now it can't find any boot device. It has 4 old SCSI drives.
So, I know how to mount a IDE or SATA drive as a slave, in a Linux environment to read data off of it (to copy the MySQL files off of it.) But, how do I do that with a SCSI drive? Also, I have an additional (identical) server to the crippled one. What will happen if I just slide one of the scsi drives into the operating server? Is this second identical server going to help me at all? I don't even know what is on it. Can I reconfigure the RAID, so it's not using a drive, and then slide in a disk from the crippled server, and copy the data off of it?

View 1 Replies View RelatedI was running Ubuntu 9.04 Desktop on a headless Pentium 4 machine which is our file, mail, web & fax server. The two x 250GB SATA hard disks were in a RAID 1 array with full disk encryption. Ran the 9.10 upgrade via WEBMIN and it failed. I should have known then to copy over everything to a backup disk, but instead I rebooted.
On restart the machine accepted my encryption passphrase but promptly hung with a mountall symbol lookup error - code 127. So I can't start the machine to get at the disks, and using a Live CD is useless as it has no way to open the RAID array to get at the encrypted partitions. Although we have data backed up (as at last night) I'd hoped not to have to rebuild the entire server from scratch. But its looking bad.I have taken one drive out and plugged it into another machine (Hercules), and the partitions show up as /dev/sdb1 /dev/sdb2 /dev/sdb3.
If it weren't for RAID, I could open /dev/sdb2 the main partition) in Disk Utility and enter my encryption passphrase to get access. But RAID adds a layer of obstruction that I have not yet overcome. I used mdadm to scan the above partitions and created the /etc/mdadm.conf file, which I edited to show the 2nd drive as missing (rather than risk corrupting both drives). I activated the RAID array with mdadm, and cat shows:
Code:
root@HERCULES# cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sdb3[0]

I've been searching the web for hours but have yet to find someone with a solution to this situation. If anyone has a thought on how to access this disk I'd be pleased to hear from you. In the meantime I will start building a new (9.10) machine from scratch, without RAID, 'cos that's probably going to be necessary.
Using a fresh copy of server 10.04 im trying to simulate a failed raid array on a pair of 2tb disks. Here is the procedure i have been following so far:
- Remove the dead disk partitions from each of the raid 1 arrays (substitute the correct md devices and partitions)
- mdadm /dev/md0 -r /dev/sdb2
- mdadm /dev/md1 -r /dev/sdb3
[code]....
I get an error here that sfdisk does not support gpt (guid partition table). I thought sfdisk did support gpt? It says to use parted, but i cant find a command that copies a partition table over from another disk in parted documentation. Any suggestions? I suppose i could make the partitions manually, but im writing a procedure for people who arent that technical and i need it to be simple enough to be run in my absence. manually building the partitions would be too hard for them.
Could 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.
I have a strange issue with my RAID5 array - it worked fine for a month, a couple days ago it didn't start on boot with mdadm reporting "Input/Output error" - I didn't panic restarted my computer, same error. Then opened a Disk utility and it reported State: Not running, partially assembled - don't know why, I've pressed Stop RAID Array and started it again, voila - it reported State: Running - I've checked components list and there was nothing wrong with it. So I run Check Array utility, waited almost 3 hours to finish it and it worked since than, till today's morning - I've started my computer, and here we go, same error.
See screenshots:
This is an initial state just after computer startup:
This is after I stop and start RAID5:
This is a components list:
I can see nothing wrong there yet not sure why mdadm fails on boot. I do not really like the windows solution I guess, when I check my array again, it will work fine again, but it then can fail in the same way without known reason.
I've got a raid5 array of 4 disks with ubuntu 8.04 runing on it that is currently still working:
/dev/sda
/dev/sdb
/dev/sdc
/dev/sdd
Smartmontools for /dev/sdc tell that there are 9 sectors pending for reallocation:
Code:
197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 9
198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 9
And /dev/sdd has increasing number of reallocated sectors (about 1 every couple of minutes):
Code:
5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 1735
/dev/sdc has failed a coulple of times this week (but I have always sucessfully readded it to raid5) . But the increasing number of reallocated sectores on /dev/sdd concerns me even more.
I'm affraid that during removal of /dev/sdd and adding new /devs/sdd disk, raid might fall appart. That's why I would try to do it in Ubuntu Live CD:If the raid falls appart (/dev/sdc fails) during the readding of new /dev/sdd disk, I might still remove the new /dev/sdd and return the previous one and assemble the raid with:
/dev/sda
/dev/sdb
/dev/sdd (old one that was previously removed)
Does assembling Raid in Ubuntu Live and adding new disk for /dev/sdd write anything on /dev/sda, /dev/sdb and /dev/sdc in the process of adding /dev/sdd into raid5?

I have a problem configuring a RAID server under Ubuntu 9.10 (kernel 2.6.31.17) with mdadm (v2.6.7.1). First I had some hardware issues that finally got solved by using another motherboard. Now I am dealing with the software part.In order to ease things, I am trying to configure a RAID 5 with three partitions in one disk. I have two HD's, one IDE where the OS lies (recognized as sda), and another where I intend to build the RAID (recognized as sdb). In this second drive I have made three partitions (sdb1, sdb2 & sdb3) of the same size.I've already re-installed Ubuntu 9.10 a couple of times, zeroed the superblocks of the partitions, repartitioned the disks with different partition sizes (I am using 5 GB partitions to save time). I've gone through this process several times, and I really don't know how to move forward now. If RAID is about trust and reliability, this is exactly what I'm not able to get.
