Hi,
NFS lock reclaiming is not working on SLES9 SP2. After the server reboot, sm-notify sends reboot notifications but the clients fail to reclaim locks.
My NFS Server and NFS client are on SLES9 SP2. My NFS server is
sgmlx1(15.70.191.172) and NFS client is sgmlx2(15.70.191.173). I mounted NFS file system on the client. Then on the client, I acquired a lock on NFS shared file using fcntl. On NFS server, an entry was made for the client in sm directory. I restarted NFS server and then
started sm-notify application. The client failed to reclaim the lock and I could acquire the lock on the same file from another client.
The reclaiming of locks was working fine on base SLES9. It started failing after I updated SLES9 with SP2.
I have captured lockd debugging messages and network tetheral trace on client and attaching the same.
Thanks for your help in advance.
Regards,
Asha

Did you try SLES9 SP3? I remember we had some problems with lock reclaim,
but I thought they were fixed in SP2.
It would be useful to get a lockd trace on the server side, what it
receives and what it sends back. The ethereal traces aren't very useful
though; it seems the snaplen is too small (and binary dumps are usually
much more helpful than the "helpful" ASCII packet representation that
ethereal or tcpdump generate)
Thanks,
Olaf

In his trace, the client wasn't sending any LOCK calls at all
for multiple minutes after receiving the NOTIFY.

Ah, you're right. I wasn't paying attention to the time stamps.
It seems the problem is that we're now using hostnames to identify lockd
peers, but you mounted the file system using the ipaddr:/path.
Could you please try the attached patch?
Thanks
Olaf

Hi Olaf,
This fix will not work for HA-NFS which allows a failover node to send the
SM_NOTIFY on behalf of the failed node.
The -v option was added for this purpose.
Marc.
