I found this from two years ago, and am wondering
- is this still the easiest thing to do?
- is this on server, client or both?
- will it break anything else?
We have a CentOS 5.4 NFS3/NFS4/samba server with about 300 clients on its
subnet, and another 100-200 on another subnet, which under high load has
started kernel-panicking (sometimes in nfsd4_cb_recall).
Have you filed a bug with the backtraces?
Duly nudged. I've posted the most recent one to
<http://bugs.centos.org/view.php?id=4229>.
I want to disable delegations to see if that cures our symptoms--but I
worry that turning leases off might cause other problems.
No, it shouldn't cause problems, at least for NFSv4 clients. (Samba may
be more reliant on leases, especially if Samba and NFSv4 clients are
acting on the same files at the same time--but I don't know.)
Thanks; no-one's grumbled just yet.
