Hi,
i've increase my number of thread nfsd 84->210->312
balsa-b# cat /proc/net/rpc/nfsd |grep th
th 312 0 10.763 1.697 1.433 0.281 0.224 0.589 0.853 2.841 0.169 0.000
balsa-b#
It's looking good for the master but i've always some problem for the
clients
***** balsa47: Commande grep nfs /var/log/messages *****
balsa47: Mar 2 10:44:26 balsa47 kernel: nfs: server balsa not
responding, still trying
balsa47: Mar 2 10:44:26 balsa47 kernel: nfs: server balsa OK
balsa47: Mar 2 10:44:27 balsa47 kernel: nfs: server balsa not
responding, still trying
balsa47: Mar 2 10:44:28 balsa47 kernel: nfs: server balsa OK
I don't understand why.
My 31 last threads are never used. Why nfs not responding.
For info my cluster is:
52 bi-xeon 2Go memory running under ES3 with nfs v2
2 master bi-PIV 2Go memory running under Redhat 7.3 with nfs v3 ( i m
waiting for 2 new master in ES3)
I use them under maya and mentalray. The node works put all the file in NFS
What happened ???
