RE: [linux-lvm] RAID1 on TOP of LVM



I had tried this with persistent-superblock 1. It had worked fine for me. I
also agree with Luca Berra.  You should use LVM on top of RAID. Any
particular reason you are using RAID on top on LVM? thx,arv.

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?

        raid-disk       1
