Hello,
I am not sure whether troubleshooting messages are allowed on the mdadm
mailing list (or it is for development and bugs only) so please point me in
the right direction if this is not the right place.
Before posting here I have tried using the following resources for
information:
Google
Distribution IRC channel (Ubuntu)
Linuxquestions.org
My knowledge of Linux is beginner/moderate.
My setup is:
9x1tb Hard Drives (2xhitachi and 7x Samsung HD103UJ)
Supermicro AOC-SAT2-MV8 8 Port SATA Card
1xMotherboard SATA port
Single RAID5 array created with mdadm, printout of /proc/mdstat:
root@server3:~# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4]
[raid10]
md0 : active raid5 sdj1[7] sdc1[0] sda1[8] sdg1[6] sdi1[9](F) sdd1[4]
sde1[3] sdh1[2] sdf1[10](F)
7814079488 blocks level 5, 64k chunk, algorithm 2 [9/7] [U_UUU_UUU]
A printout of /var/messages is available here: http://pastebin.com/m6499846
as not to make this post any longer...
(The array has been down for about a month now. It is my home storage
server, non-critical, but I do not have a backup)
Also a printout of ‘mdadm --detail /dev/md0’ is available here:
http://pastebin.com/f44b6e069
I have used ‘mdadm -v -A -f /dev/md0’ to get the array online again, and can
read data (intact without errors) from the array, but it soon becomes
degraded again.
Any help on where to start would be greatly appreciated :)
Jack
What kind of MB do you have on this setup?
And that card is in a PCI-X slot isn't it?
And how big of power supply do you have? What is the rating of the
Amps on the +12V line?
And is it always the same disks or disks that fault, or is any disk
just as likely to have issues?
