From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Gordon Mohr (@ Bitzi)" Subject: Questions: understanding fail/remove steps from RAID1 Date: Sat, 12 Feb 2005 14:11:07 -0800 Message-ID: <420E7EFB.4000303@bitzi.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-raid-owner@vger.kernel.org To: linux-raid@vger.kernel.org List-Id: linux-raid.ids 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, - Gordon
