another annoying cause of disks being kicked from mdadm (and zfs and presumably btrfs arrays too) is disk read timeouts due to the drive sleeping.
Not just sleeping, "consumer" drives apparently try much harder to recover from dodgy sectors, up to 2 minutes for some drives so I'm told. "Enterprise" drives give up much quicker in the assumption that they're in a RAID array. Not surprisingly RAID code tends to not be very tolerant of disks that take so long to respond.. cheers, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC This email may come with a PGP signature as a file.
