Hi, Whenever I reboot my server (kernel 2.6.6) the raid (level 5) comes back in degraded mode. The missing disk is hdd3 and is correctly set out in the raidtab. The output of lsraid shows the superblock of hdd3 differs to those of the rest of the disks in the array, as shown below. Does anyone have any ideas? After a raidhotadd /proc/mdstat corresponds to the raidtab, as does the ouput of lsraid -d for any device in the raid. At the moment this means that if I lose a disk my raid will be trashed since I will have two disks missing, so this relaly needs fixing. Hope someone has an idea, thanks in advance!
