Possibly, but I don't like to bother others when I don't need to. And in the beginning I didn't connect this behavior whit kernel but with some hardware disk issues. Moreover reporting bugs on list is hmm... inconvenient. Please, back Bugzilla online ASAP. > If you have all important data backed up then just upgrade to 3.1.2 > and make > the array again from scratch.

If some of system survive, I can make it up faster. Of course, if it isn't to complicated or take too much of your time to describe it. mdadm --examine /dev/sda2 /dev/sda2: Magic : a92b4efc Version : 0.90.00 UUID : 0f01ef9e:ab0117cf:3d186b3c:53958f34 (local to host (none)) Creation Time : Wed Aug 17 09:34:04 2011 Raid Level : raid10 Used Dev Size : 1463946752 (1396.13 GiB 1499.08 GB) Array Size : 5855787008 (5584.51 GiB 5996.33 GB) Raid Devices : 8 Total Devices : 7 Preferred Minor : 1 Update Time : Tue Nov 22 11:43:58 2011 State : clean Active Devices : 6 Working Devices : 7 Failed Devices : 2 Spare Devices : 1 Checksum : e8423abc -
