I've been experiencing as-yet-undiagnosed kernel panics on a server with two RAID1 arrays. (x86_64; 2.6.10 FC3 kernel; Promise SATA with Seagate drives.)
After a recent panic and reboot, the two RAID1 arrays dropped their member partitions from a certain drive (sdb).
Based on previous experience with simulated failures, I had expected the devices to still be listed by name as part of the array, but as failed/faulty. Instead, they were not listed in either /proc/mdstat or 'mdadm --detail' output.
Were my expectations wrong -- is this by design?
Looking over /var/log/messages, there's no clear indication of a specific time or reason the sdb partitions were dropped from the array.
Are raid array events logged somewhere else?
Thanks for any insights,
