I will be watching this thread with great interest as I am in a
similar situation. Right now, my plan is to share the disks on the two
servers using DRBD providing a RAID-1 and then share the DRBD volume
using GFS. As per my little understanding, you will have to use CLVM
to make sure you don't run into other issues. I have yet to test this
configuration though.
