Suspend kills RAID-5 array
Last modified: 2008-05-06 12:19:41 EDT
Clicking Suspend in the GNOME menu causes multiple drive failure in
a RAID-5 array. My root filesystem is on a RAID-5 array and when I
clicked Suspend I heard the 4 drives of the array parking heads and
spinning down one-by-one. Wakeup failed to start the drives so I did
a hard reset and the system no longer was able to boot because two
drives were kicked out of the array. I had to boot from the install
DVD and in rescue mode manually assemble the array with:
mdadm -A --force /dev/md0 /dev/sda3 /dev/sdb3 /dev/sdc3 /dev/sdd3
Does anybody know how to disable this suspend feature?
Not sure what we can do from userland to properly detect those cases and do
something correctly as in this case where / is on a RAID5 this would have to
happen properly during suspend in the kernel itself.
Reassigning to kernel, maybe they have a better idea how to fix it.
Read ya, Phil
