Subject: [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

nr-spare-disks 0

failed-disk 0
device /dev/MKP.1/1
raid-disk 1
========= output of mkraid in single user mode =========
# mkraid /dev/md0

disk 0: /dev/MKP/1, failed
