Are the raidtools still maintained, or at least bugs corrected ? here is what happens, as you can see, my /dev/md2 is composed of /dev/hda3, /dev/hdb3, /dev/hdc3, that are reported right while offline, but /dev/hdc3 is shown as /dev/null while online :-( [root@ge raidtools-1.00.3]# raidstop /dev/md2 [root@ge raidtools-1.00.3]# ./lsraid -R -p | grep md2 -A 13 # md device [dev 9, 2] /dev/md2 queried offline # Authoritative device is [dev 22, 3] /dev/hdc3 raiddev /dev/md2 raid-level 5 nr-raid-disks 3 nr-spare-disks 0 persistent-superblock 1 chunk-size 128 device /dev/hda3 raid-disk 0 device /dev/hdb3 raid-disk 1 device /dev/hdc3 raid-disk 2 [root@ge raidtools-1.00.3]# raidstart /dev/md2 [root@ge raidtools-1.00.3]# ./lsraid -R -p | grep md2 -A 13 # /dev/md2 # /dev/sda # /dev/sda1 # /dev/sda2 # /dev/sda3 # /dev/hdc # /dev/hdc1 # /dev/hdc2 # /dev/hdc3 # /dev/hda # /dev/hda1 # /dev/hda2 # /dev/hda3 # /dev/hdb -- # md device [dev 9, 2] /dev/md2 queried online raiddev /dev/md2 raid-level 5 nr-raid-disks 3 nr-spare-disks 0 persistent-superblock 1 chunk-size 128 device /dev/hda3 raid-disk 0 device /dev/hdb3 raid-disk 1 device /dev/null failed-disk 2 Additionnaly, you can see clearly that /dev/hdc3 is not in a failed state: kalou@ge cat /proc/mdstat | grep -A1 md2 md2 : active raid5 hdc3[2] hdb3[1] hda3[0] 120246272 blocks level 5, 128k chunk, algorithm 0 [3/3] [UUU] Olivier - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
