Hi
I'm having trouble setting a very simple cluster with 2 nodes. After all
reboot I'm getting split brain that I have to solve by hand then.
Looking for a solution for that one...
Both nodes have 4 network interfaces. We use 3 of them: one for an IP
cluster, one for a bridge for a vm and the last one for the private
network of the cluster
I'm using
drbd : 8.3.9
drbd-utils: 8.3.9
DRBD configuration:
============
$ cat global_common.conf
global {
usage-count no;
disable-ip-verification;
}
common { syncer { rate 500M; } }
cat server.res
resource server {
protocol C;
net {
cram-hmac-alg sha1;
shared-secret "eafcupps";
}
on dzacupsvr {
device /dev/drbd0;
disk /dev/vg0/server;
address 172.16.1.1:7788;
flexible-meta-disk internal;
}
on dzacupsvr2 {
device /dev/drbd0;
disk /dev/vg0/server;
address 172.16.1.2:7788;
flexible-meta-disk internal;
}
}
Pacemaker configuration

and here are the logs

After looking for more information, I've added fences in drbd configuration
handlers {
fence-peer "/usr/lib/drbd/crm-fence-peer.sh";
after-resync-target "/usr/lib/drbd/crm-unfence-peer.sh";
}
but still without any success...
Any help appreciated
Cheers
