The sample /etc/raidtab is different in the HOWTO compared to the sample
/etc/raidtab given in version 0.9 of the raidtools.
I got the 2.2.14 kernel patch and 0.90 version of the raidtools from
http://people.redhat.com/mingo/raid-patches/
I also picked up the latest version of the Software RAID HOWTO
http://ostenfeld.dk/~jakob/Software-RAID.HOWTO/
In the raidtools, it gives a sample /etc/raidtab conf file as
$ cat raid1.conf.sample
# Sample raid-1 configuration
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 4
device /dev/hda1
raid-disk 0
device /dev/hdb1
raid-disk 1
In section 4.5 of the HOWTO from ostenfeld.dk it also has a superblock option (fig 1)
listed which
does not work when I try to do a mkraid (fig 2) on the device.
fig 1:
Set up the /etc/raidtab like this:
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 4
persistent-superblock 1
device /dev/sdb6
raid-disk 0
device /dev/sdc5
raid-disk 1
fig 2:
mammoth:/# mkraid /dev/md0
unrecognized option peristent-superblock
detected error on line 9:
peristent-superblock 1
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
