Hi,
I need some help with NFSv4 setup/tuning. I have a dedicated nfs server
(2 x E5-2620 8cores/16 threads each, 64GB RAM, 1x10Gb ethernet and 16x
8TB HDD) used by two servers and a small cluster (400 cores). All the
servers are running CentOS 7, the cluster is running CentOS6.
Time to time on the server I get:
kernel: NFSD: client xxx.xxx.xxx.xxx testing state ID with
incorrect client ID
And the client xxx.xxx.xxx.xxx freeze whith:
kernel: nfs: server xxxxx.legi.grenoble-inp.fr not responding,
still trying
kernel: nfs: server xxxxx.legi.grenoble-inp.fr OK
kernel: nfs: server xxxxx.legi.grenoble-inp.fr not responding,
still trying
kernel: nfs: server xxxxx.legi.grenoble-inp.fr OK
There is a discussion on RedHat7 support about this but only open to
subscribers. Other searches with google do not provide useful
information.
FYI - you can get access to such info with a free RHEL developers
account.
Thanks for your suggestion. As the problem is back I've subscribed to
reach the full content of this discussion.
The answer was "do not use antivirus" :-(. I do not use antivirus as I
am CentOS only.

Just curious to see if you have had any luck resolving these issues?
I'm afraid that NFS on EL 7 has become much less stable for us recently
as well with lots more client access hangs.
