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?

honestly i'd use lvm over raid1, it is most flexible since raid1 is not resizable.
