Hello,
tonight the unthinkable happend and two drives in a four drive raid 5
went offline within one hour.
I deactivated the raid, turned the computer off and rebooted. I checked
both drives and they are fine.
The raid consists of sdb1, sdc1, sdd1 and sde1.
sdd1 failed first, then sde1.
I use kernel 2.6.18.2 with raidtools 1.00.3-r6.
After reading through the howtos and archives the following should be
the proper way to rescue the raid 5:
mark first failed drive as failed-disk, so my new raidtab entry should
look like this:
====
raiddev /dev/md10
raid-level 5
nr-raid-disks 4
nr-spare-disks 0
persistent-superblock 1
chunk-size 64k
parity-algorithm left-symmetric
device /dev/sdb1
raid-disk 0
device /dev/sdc1
raid-disk 1
device /dev/sdd1
failed-disk 2
device /dev/sde1
raid-disk 3
====
#mkraid --force /dev/md10
mark failed-disk as raid-disk and raidhotadd it.
Is this the right way to do it without screwing the array up?
Thanks & ciao,
Elmar Weber
