Hi, trying to set up a HA NFSv4 Cluster I found some problems in the last year. 1) The cluster has to release the existing locks after a failover. This is only possible in recent kernels. I do not know if this is possible in CentOS. 2) Only recent exportfs resource agent gives you the possibility to release the locks. Perhaps you would have to compile your own cluster-agents package. 3) Fedora 16 (which comes with a recent kernel) moved from the init system to systemd. pacemaker cannot handle systems. So you cannot start the nfs server under cluster control. You can work around this using the respan option of systemd. 4) Debian-based distribution seem to have problems with the locks. But I do not know exactly. 5) You could try with opensuse. Please mail me about your advances. I am interested.
