Hello Alan,

This is my current setup:

Xen DomU

DRBD

LVM Volume

RAID 1

What I first wanted to do was:

DomU | DRBD

LVM Volume

RAID 1

If I understand you diagram, you have DRDB running inside your domU with LVM on top of it now, and you are considering moving DRDB out of the domU into your dom0. Yes, it should work, and yes, you'll have to change the domU config to map the drbd block device into the domU. Am hoping a vgscan on the domU will pick up the fact you will be effectively changing the physical device names. I think the arrangement of doing DRDB and LVM at the dom0 level, and mapping LVs out of that as domU disks is not an uncommon implementation. -Alan
