Hi,
I am currently working on set up a NFS Cluster with DRBD, but I am running into some issues with pacemaker and nfs. I have removed /var/lib/nfs (I am on CentOS 5.5) and create dir called /data/cluster/nfs, and I created a link back to it….
ln –s /data/cluster/nfs /var/lib/nfs
I did remove rpc_pipefs to /var/lib/ and updated /etc/modprobe.conf.dist to point to it.
Now I did create 500MB Slice in DRBD for /data/cluster/nfs, format it to ext3 and copied of all the stuff from there to it.
I set up the slice a primary on both so that I can have that dir on both nfs server. I did this because NFS seems have a tuff time shutting down and moving the drbd device over.
I have them set up in pacemaker, and when I do a start of heartbeat, it move nfs and vip, but not nfslock. Now on the second know if I restart heart nothing gets moved, but nfslock starts.

What is the trick to get NFS working with pacemaker.
