Is there an up to date document detailing the configuration of an NFSv4 cluster service on a 2-node RHEL 5.3 Cluster Suite setup? Most of the info I find is from 2006/2007 and states that these features are in a state of flux and could change soon.
My current configuration is 2 nodes, RHEL 5.3 (kernel 2.6.18-128.1.14.el5PAE), SAN attached shared storage, with GFS2 file systems.
I read the documents at:
And also the NFS cluster cookbook and Red Hat’s NFS cluster example. The former two are fairly old, and the latter two documents seem fairly basic and don’t address certain issues like:
Also, when mounting my NFS shares using the cluster’s virtual IP address or name, I get some errors in my NFS server’s logs regarding timed out callbacks:
Jun 25 15:00:12 node2 kernel: nfs4_cb: server <CLIENT1 IP ADDRESS> not responding, timed out
Jun 25 17:07:37 node2 kernel: nfs4_cb: server <CLIENT2 IP ADDRESS> not responding, timed out
If I mount the file system using the cluster node’s static address/name, these errors don’t appear, but for obvious reasons, this is undesirable.
