I don't know how this could be correct or how you could land with such a config. @md: The problem is following: Lennart has a raid 1 on 3 disks, however raid_disks in sdd2 is 2 and dev_roles contains only [0, 1, -1, -1, ...], dev_number is 0 sda2 and sdb2 contain proper raid_disks=3D3, dev_roles=3D[0,1,2,-1,-1,..]= and dev_number=3D 0 respectively 1. It looks to me as a seriously damaged= metadata but apparently mdadm has no problem @Lennart: did you dd one disk to another or done something like this? root@rceng03new:~# mdadm --detail /dev/md0 /dev/md0: Version : 1.2 Creation Time : Wed Feb 8 14:39:24 2012 Raid Level : raid1 Array Size : 976884 (954.15 MiB 1000.33 MB) Used Dev Size : 976884 (954.15 MiB 1000.33 MB) Raid Devices : 3 Total Devices : 3 Persistence : Superblock is persistent Update Time : Thu Mar 1 15:02:06 2012 State : clean Active Devices : 3 Working Devices : 3 Failed Devices : 0 Spare Devices : 0 Name : rceng03new:0 (local to host rceng03new) UUID : 88d43dc8:2888fece:34c1486f:49caa398 Events : 74 Number Major Minor RaidDevice State 0 8 2 0 active sync /dev/sda2 1 8 18 1 active sync /dev/sdb2 2 8 50 2 active sync /dev/sdd2 --=20 Regards Vladimir '=CF=86-coder/phcoder' Serbinenko --------------enig9497CE2387B78402AD830A34 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iF4EAREKAAYFAk9aSM8ACgkQNak7dOguQgka4QEAuBICzxpiBeXiJKT4gyBTeZyy R1BdNB5fZ7xaAm86IRIA/irNWJjYI6C7tJj9Dc7mkFlHHvM2JoNZd9J87/AduSwc =Mbiq -----END PGP SIGNATURE----- --------------enig9497CE2387B78402AD830A34--
