I try to set up a RAID 1 mirror made up of 2 SCSI drives 4MB each.
The drives are connected to te system via an AIC78xx controller that
works just fine with single disks. Each disk has one singe partition
that covers the whole disk. According to the Software-RAID HOWTO,
i changed the patition type of both disks to 'fd' = Linux RAID.
The disk patitions were wiped completetly, so 'mkraid' doesn't
complain about existing file systems.
There is a /etc/raidtab as follows
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 4k
persistent-superblock 1
device /dev/sda1
raid-disk 0
device /dev/sdb1
raid-disk 1
The kernel is 2.2.13 built with static RAID support.
Inspecting /proc/mdstat shows
Personalities : [1 linear] [2 raid0] [3 raid1] [4 raid5]
read_ahead not set
md0 : inactive
md1 : inactive
md2 : inactive
md3 : inactive
Now i try to run mkraid (Version 0.9): mkraid /dev/md0
it dies like this:
--------------
handling MD device /dev/md0
analyzing super-block
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
--------------
Of couse, neither /dev/mdstat nor syslog show _anything_.
Next step was to make mkraid a little more verbose by adding abort
messages. So i got this:
---------------
handling MD device /dev/md0
analyzing super-block

Ha, the ioctl call to SET_ARRAY_INFO is broken !
Can anybody please tell me, what i might have done wrong ?
