Yes it all works fine. I have a very similar setup.
DRBD 8.0pre6 (or rc1) in primary/primary mode
LVM2 (with RH Cluster extensions)
Xen
What is the output of /proc/drbd on both machines? Looks like they don't have a cstate of connected...

Subject: [DRBD-user] DRBD8 on LVM2 + Xen
Hi all,
Short: Can I use DRBD8 on a LVM LV? I'm getting an error: "Failure: (114) Lower device is already mounted."
Long: I have the following setup:
A Xen dom0 in which I create several LV's for usage with Xen domU's. (This is very convenient on Debian Etch with the xen-create-image utility, using the --lvm switch.) I create a seperate LV which I dedicate to the Xen domU like so:
'phy:sys/drbd1-drbd,hdb1,w'
I don't mount this partition in the domU, but I try to connect to it with drbd8-pre5 (Etch package). The relevant part of the drbd.conf:
on drbd1 {
device /dev/drbd0;
disk /dev/hdb1;
address 172.21.1.20:7788 ;
flexible-meta-disk internal;
(If you need more info about the drbd config, please let me know!)
When I try to start drbd, I get the following message:
tim at drbd1:~$ sudo /etc/init.d/drbd start
Starting DRBD resources: drbd: initialised. Version: 8.0pre5 (api:84/proto:83)
drbd: SVN Revision: 2481M build by root at drbd1, 2007-01-03 10:10:53
drbd: registered as block device major 147
[ d0 Failure: (114) Lower device is already mounted.
s0 n0 drbd0: conn( StandAlone -> Unconnected )
drbd0: receiver (re)started
drbd0: conn( Unconnected -> WFConnection )
(after which the counter starts counting, since the second machine isn't online)
What am I doing wrong here? I got this setup working with drbd0.7, but I noticed it's due to be removed from Debian, so I figured, I'd better move to drbd8.
Any help/advice is greatly appreciated.
