Hi,
we're a redhat/fedora based install, thus use anaconda, and as such...

Are you using -o nolock when you're mounting? This caused problems for us, a few years ago, iirc.

I tend to disable everything I don't know I need ;)
I guess I assumed that NFS locking would be necessary for things like exclusive access to NFS-mounted mailboxes, but not much else. we don't do mail on clusters at all, and I don't think any of our users are doing flock/lockf-type stuff on their files. oh, right, and my nfsroot is also
readonly (as exported from the server), so I figured locking was irrelevant.
(and forgot about the 'rw' tucked away in the initrd...)

what kind of problems did you run into?

This goes back a few years, so memories are fuzzy, but we found that when we went to update from RH9 to FC3 on our cluster, NFS performance during anaconda kickstarts was rediculously slow... we found timeout issues waiting for locking (iirc, I don't remember if we had so sniff this problem, or were able to catch errors on one of the virtual terms)... the end result was that for our anaconda installs, we needed to do -o nolock mounts.

Cheers,
Paul
