Has anyone ever used DRBD on top of LVM devices ? Has anyone had a
problem with this? Such that can grow and move around partiions etc,
and not have to use NFS on top of DRBD with spare files for storage.
Or can someone recomened a better way of doing with with no attached
shared storage.
Each server has its own hard drive, and should mirror each other.

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.
Ah i remember reading about this a year ago when i first heard about
it. 0.8 has been in devolpment for a long time. How stable has it
been for you? I really would like to avoid doing NFS :-) (as i kick
our NFS appliance on our Compute cluster)
