Raid recovery - raid5 - one active, two spares

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Encouraged via information found on the wiki
<https://raid.wiki.kernel.org/index.php/RAID_Recovery> it would be
great to receive advice from linux-raid community.

Recently I bought a extra hard drive (next to existing raid level 5
three discs). Unfortunately during physical installation probably
disconnect two hard drives of existing raid on my PC. I didn't notice
that cables was not properly inserted. After system bootup (Linux Mint
13) md doesn't start. Because /home directory should be mounted on
LVM@RAID my system doesn't start properly

I've disconnected new hard drive, check and correct every cable on
previously working hard drives and run LiveUSB linux to check if RAID
will go OK. It wasn't.

>From liveCD perspective raid 5 should be worked on three partitions:
/dev/sdb1
/dev/sdd1
/dev/sde1

There are also other storage devices on PC:
/dev/sda - main drive, system without /home
/dev/sdc - LiveUSB usb

It is possible to recover Raid 5 from this disks? I consider
"Restoring array by recreating..."
<https://raid.wiki.kernel.org/index.php/RAID_Recovery#Restore_array_by_recreating_.28after_multiple_device_failure.29>
but I would like to know Your opinion. According to wiki it should be
considered as *last* resort.

P.S. Fortunately I have a backup, but time spend on recover can take
much longer.

Best regards,
