Cannot Start Dirty Degraded

Most servers in RaW will have at least one Software RAID array for redundancy. Must be active md2 to can be mounted? It has been 2 days and I cannot detect any issues with the original fault. EDIT: Source Code ~# cat /proc/mdstat Personalities : [raid6] [raid5] [raid4] md126 : active (auto-read-only) raid5 sdb[0] sdc[3] sdg[2] sdd[4] 2930284032 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/4] http://culturahq.com/cannot-start/cannot-start-dirty-degraded-array-for-md2.html

Then... as documented in the /usr/linux/Documentation/md.txt (cwilkins post). If some are marked as removed or failed then you'll have to deal with the failed disks first. DEVICE partitions # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST # instruct the monitoring http://www.linuxquestions.org/questions/linux-general-1/raid5-with-mdadm-does-not-ron-or-rebuild-505361/

md: pers->run() failed ... Edit: My /etc/mdadm/mdadm.conf looks like this. I'll calm down.

Ok, I'm a Linux software raid veteran and I have the scars to prove it (google for mddump if you're bored), but that's not doing me much good now. This morning I found that /dev/sdb1 had been kicked out of the array and there was the requisite screaming in /var/log/messages about failed read/writes, SMART errors, highly miffed SATA controllers, etc., Disclaimer: if it has one and if it is connected. Originally built with mdadm.

I powered off and now I don't see this raid in OMV and got error at Filesystems. I'll calm down. Adverb for "syntax" What are the applications of taking the output of an amp with a microphone? you could check here Last edited by HellesAngel; 10-11-2009 at 04:17 PM.

Needless to say the reboot resulted in some shock as one of the raid partitions (in my case 2.6TB MD3) was 'inactive'. All the tests are errors pretty much line up exactly.

I was unsuccessful, but perhaps someone here can adviseme where I went wrong.When I boot, I see the "Starting up RAID devices: ... * Tryingmd0...

Anyway I followed the ideas presented here and was soon looking at the best bit of news possible: [email protected]:/home/andy# cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] SATA cable.

So after that, I did the following: Code: umount /data Code: mdadm /dev/md0 -a /dev/sdb1 The drive was added without error.

I am hoping you guys could help me avoid this. When I did dmesg | tail , it said something about /dev/sda1 containing unsupported features.

syscall_call+0x7/0xb [] ? Hope this will help some people. My hunch is that the problem stems from the superblock indicating that the bad device is simply "removed" rather than failed. Once you have a shell, you can run mdadm to attempt to recover your RAID array.
