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.
