--- Begin Message ---Package: mdadm Version: 2.6.7-3 Severity: important File: mdadm Hi, A friend of mine had a problem with a system that refused to boot properly after losing power during a RAID-6 reshape. After some fiddling and newer mdadm, we crashed into the problem that mdadm simply segfaulted on assemble. The backtrace showed that it was crashing in match_home0, in memcmp(), since st->sb was NULL. I didn't debug it a lot further (I don't know the inner workings of mdadm; if it helps, "st" was NULL on Assemble() entry), but simply giving the right superblock type (0.90) on the command line made the RAID assemble and continue reshaping, so I assume the bug is somehow in the superblock detection. FWIW, here's a superblock from one of the disks before assembling: /dev/sda1: Magic : a92b4efc Version : 00.91.00 UUID : c568c44e:0c9c4ba5:c8cfeb02:e466cd1e Creation Time : Tue Jun 10 06:43:48 2008 Raid Level : raid6 Used Dev Size : 976759936 (931.51 GiB 1000.20 GB) Array Size : 2930279808 (2794.53 GiB 3000.61 GB) Raid Devices : 5 Total Devices : 5 Preferred Minor : 6 Reshape pos'n : 1276426944 (1217.30 GiB 1307.06 GB) Delta Devices : 1 (4->5) Update Time : Sat Sep 6 16:46:16 2008 State : clean Active Devices : 5 Working Devices : 5 Failed Devices : 0 Spare Devices : 0 Checksum : 8be433d0 - correct Events : 282948 Chunk Size : 64K Number Major Minor RaidDevice State this 2 8 1 2 active sync /dev/sda1 0 0 8 17 0 active sync /dev/sdb1 1 1 8 49 1 active sync /dev/sdd1 2 2 8 1 2 active sync /dev/sda1 3 3 8 33 3 active sync /dev/sdc1 4 4 8 97 4 active sync /dev/sdg1
