NFS errors in /var/log/warn...

martinprowe · February 28, 2014, 1:19pm

I am using OpenSuSE 13.1 clients and a 12.1 NFS server (NFS4 turned off). Although the NFS shares are mounted (via fstab) and seem to work fine, I am getting lots (hundreds!) of error messages.
Like these:

2014-02-28T11:05:10.755781+00:00 gzunder rpc.gssd[29740]: ERROR: can't open /var/lib/nfs/rpc_pipefs/gssd/clntXX/info: No such file or directory

2014-02-28T11:05:10.757723+00:00 gzunder rpc.gssd[29740]: ERROR: failed to read service info

The path to** /var/lib/nfs/rpc_pipefs/gssd/clntXX/** is there but there is no “info” file. Should there be?
Why is gssd (NFS4/Kerberos related?) even trying to read service info?
There are no relevant errors at the server. Not knowing where to look, this is the only diagnosis I can think of:

And again at the server:

Any advice to “clean up” my config would be most welcome.

Recommend you start by inspecting the version of NFS running on your 13.1 and 12.1, my guess is that they will be <very> different.
If so, try to update to as current as possible. Of course, that will likely be next to impossible on 12.1, you should strongly consider upgrading it to 13.1 as well.

Check /etc/nfsmount.conf, look for


# Defaultvers=4

change it to


Defaultvers=3

I saw this at a customer’s, IIRC this stopped the messages

Hmmmm…
Not sure about the logic of this approach? NFS is a standard (of sorts) the client/server versions shouldn’t make any difference.
And in fact, I see these errors on a clean 13.1 install without ever connecting to a NFS server.

Hi Knurpht,

Thanks for the suggestion. But no, made no difference.
