Hello !

I'm using XEN 3.0.2-3 with Kernel 2.6.16.29 on Ubuntu Dapper Server 6.06
with a XEN DomU on a DRBD Device (Version 8.0pre6) on LVM. It's in
production only since Sat, Nov 11.

I didn't try to resize the underlying LVM device but I'm taking daily
snapshots and do rsync backups of the snapshots.

This works for me, but check out drbd.org and the DRBD changelogs
because afaik DRBD on LVM is supported only in the 8.0pre series not in
the stable 0.7.X.

In the changelog of 8.0 you find an entry:

8.0pre3 (api:82/proto:80)
--------
 * Now it works on device mapper (LVM) as well as on "real" block devices.
 * Finally (after years) a sane "drbdadm adjust" imprementation, which is
   really really robust.
