Hi
We recently switched to nfs3 from nfs4 and now we're getting lots of
lockd errors. We can remove the error by mounting with:
-o local_lock=posix
We had to switch to be able to use the posix acl we had set on the share.
What problems may we face by setting the local_lock?
Thanks,
Steve
Hi
Sorry to bump
This is openSUSE 12.1. All the references to lockd probs seem to come from 10 or so years ago.
Could anyone give me a one liner as to where to start looking? I've gone through all the usual channels.
Cheers,
Steve
Server:
Mar 5 16:24:46 hh3 kernel: [16760.656609] lockd: cannot monitor hh6
This error message means "hh3" cannot monitor "hh6". Usually that's a sign that rpc.statd on hh3 is having trouble getting a clean DNS lookup of hh6. Maybe enabling debugging on statd would produce a little more diagnostic information.
Hi Chuck
Thanks for the reply. You've got me on the right track. Running at both
ends in the foreground is rock solid and instantaneous:

Dropping to daemon makes the errors reappear with slow file transfer.
I've also nailed the Thunar file manager under XFCE which seems to be
making calls to cifs via Kerberos each time we request a file ??. With
Nautilus it's fine. The nfs/server principal is called once at the start
of the session with no cifs requests.
Just one quick question, does the client server statd output look OK?
Thanks,
Steve
