I'm running 2.2.12 and raidtools/patches from 19990824.
I'm trying to create a raid-1 partition with the "failed-disk" feature
to transfer existing data from one of the partitions.
raiddev /dev/md6
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 64
persistent-superblock 1
device /dev/sdb6
raid-disk 0
device /dev/sda6
raid-disk 1
failed-disk 1
So I have sda6 mounted (shouldn't be a problem) and try to
create the raid partition:
% mkraid /dev/md6
handling MD device /dev/md6
analyzing super-block
disk 0: /dev/sdb6, 6964146kB, raid superblock at 6964032kB
disk 1: /dev/sda6, failed
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
Hmm, syslog messages are:
Sep 29 05:10:08 carve kernel: bind<sdb6,1>
Sep 29 05:10:08 carve kernel: blkdev_open() failed: -19
Sep 29 05:10:08 carve kernel: md: [dev 00:00] has zero size, marking faulty!
Sep 29 05:10:08 carve kernel: md: error, md_import_device() returned -22
% cat /proc/mdstat
Personalities :
read_ahead not set
md6 : inactive sdb6[0] 0 blocks
unused devices: <none>
Any ideas what's wrong here?
Both disks are identically partitioned:
Disk /dev/sda: 255 heads, 63 sectors, 1106 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 9 72261 83 Linux
/dev/sda2 10 1106 8811652+ 5 Extended
/dev/sda5 10 140 1052226 83 Linux
/dev/sda6 141 1007 6964146 83 Linux
