Re: strange RAID5 problem

Good evening.

I am having a bit of a problem with a largish RAID5 set.
Now it is looking more and more like I am about to lose all the data on
it, so I am asking (begging?) to see if anyone can help me sort this out.

Very thorough description, but you omitted the 'dmesg' output
corresponding to :

[root@box ~]# mdadm
--assemble /dev/md3 /dev/sdq1 /dev/sdr1 /dev/sds1 /dev/sdt1 /dev/sdu1
/dev/sdv1 /dev/sdx1 /dev/sdy1 /dev/sdz1 /dev/sdaa1 /dev/sdab1 /dev/sdac1
/dev/sdad1 /dev/sdae1 /dev/sdaf1
mdadm: failed to RUN_ARRAY /dev/md3: Invalid argument

Also, you don't seem to have tried '--force' with '--assemble'.  It
might help.
