I am puzzled by an sles9sp3 (2.6.9 kernel) nfs server that serves rhel3 (2.4.21 kernel) compute nodes. For some reason a lot of times the mounts fail (with default as well as modified parameters). The symptom is mount: rpc timeout. The server logs all authentification requests as successful. The switch is an oversubscribed hp 4108gl.
Google turned up nothing useful.
Any ideas?
Michael

Exactly.

Nice, any sort of comparison data in terms of differences in
throughput achieved?
Additionally, are you writing your journal to a different partition?
Thanks,
