Since two weeks im trying to remount a Sofraid (Level1) which I created with mdadm -Cv /dev/md3 -l1 -2 /dev/sdc1 /dev/sdd1 When I boot the system, debian (3.1, kernel 2.6.16.1) tells me, that the reiserfs on the raid has a bad superblock. When I recrate the raid and check it by mdadm I get the following different messeges: bash:~# mdadm -Q /dev/md3 /dev/md3: 186.31GiB raid1 2 devices, 0 spares. Use mdadm --detail for more detail. /dev/md3: No md super block found, not an md component. bash:~# mdadm --detail /dev/md3 /dev/md3: Version : 00.90.03 Creation Time : Wed Apr 12 15:49:28 2006 Raid Level : raid1 Array Size : 195358336 (186.31 GiB 200.05 GB) Device Size : 195358336 (186.31 GiB 200.05 GB) Raid Devices : 2 Total Devices : 2 Preferred Minor : 3 Persistence : Superblock is persistent Update Time : Wed Apr 12 15:49:46 2006 State : active, resyncing Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Rebuild Status : 4% complete UUID : 2cb624fd:38e44c54:716ab7c2:c6c0e8c3 Events : 0.2 Number Major Minor RaidDevice State 0 8 33 0 active sync /dev/sdc1 1 8 49 1 active sync /dev/sdd1 ---------- I?m having other softraids, wich are created by the installationsroutine of sarge. These raids are working properly. My /etc/mdadm/mdadm.cong looks like this: DEVICE partitions ARRAY /dev/md2 level=raid1 num-devices=1 spares=1 UUID=fd3f5565:700efa41:9c649802:f9165970 devices=/dev/sda4,/dev/sdb4 ARRAY /dev/md1 level=raid1 num-devices=1 spares=1 UUID=ce956e77:bb6dfc5c:052c5d48:90ccc5a5 devices=/dev/sda3,/dev/sdb3 ARRAY /dev/md0 level=raid1 num-devices=1 spares=1 UUID=5f5bc322:fe00157d:7f574758:88afc009 devices=/dev/sda2,/dev/sdb2 ARRAY /dev/md3 level=raid1 num-devices=1 spares=1 devices=/dev/sdc1,/dev/sdd1 A part of the bootlog in /var/log/messages : Apr 12 15:36:39 localhost kernel: ReiserFS: md3: warning: sh-2006: read_super_block: bread failed (dev md3, block 2, size 4096) Apr 12 15:36:39 localhost kernel: ReiserFS: md3: warning: sh-2006: read_super_block: bread failed (dev md3, block 16, size 4096) Apr 12 15:36:39 localhost kernel: ReiserFS: md3: warning: sh-2021: reiserfs_fill_super: can not find reiserfs on md3 I have surely created a reiserfs on the raid, and I have waited till the sync is done before I restarted the machine.
