hi, I have to scsi disks that are the same size and have the same parititon sizes. when I go mkraid /dev/md0
handeling MD device /dev/md0
analyzin super-block
disk0: /dev/sda1, 979933kb, raid superblock at 979840kB
disk1: /dev/sdb1, 979933kb, raid superblock at 979840kB
md: could not lock sda1.
md: error, md_import_device() retured -16
mkraid: aborted.
-----------------------------------------------------------------------
my raidtab file looks like this
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 4
persistent-superblock 1
device /dev/sda1
raid-disk 0
; device /dev/sdb1
raid-disk 1
raiddev /dev/md1
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 4
persistent-superblock 1
device /dev/sda2
raid-disk 0
; device /dev/sdb2
raid-disk 1
