[linux-lvm] RAID1 on TOP of LVM



Hi,

I have had LVM for a little while now.
I have even successfully extended an LV.  Moved PVs.
And better yet.  Destroyed and recreated an LV containing Data :-)
The final step, RAID1.  But I stumbled.
Can someone help?

========= /etc/raidtab file =========
raiddev /dev/md0
        raid-level      1
        nr-raid-disks   2
        nr-spare-disks  0
        chunk-size      4
        persistent-superblock 0
        device          /dev/MKP/1
        failed-disk     0
        device          /dev/MKP.1/1
        raid-disk       1

========= output of mkraid in single user mode =========

    # mkraid /dev/md0
