nfs client ls /data/rw10
nfs client on mount: Permission denied
807557May 9 2008 — edited May 10 2008We are running an 800 cpu amd solaris 10 x64 cluster for HPC and an 512 cpu ultrasparc cluster solaris 10 for high
throughput.
Until now the nfs servers played ball and I did not experience real difficulties.
I am running two Solaris 10 x64 servers serving a total of 80 TB over nfs4, one Thumper serving 17 TByte over nfs4
and 7 linux serving 30 TByte over nfs3.
Today for the first time I got a massive rejection of mounts with the following error on the client.
May 9 18:24:10 m2001 nfs: [ID 664466 kern.notice] NFS compound failed for server c-store2: error 12 (RPC: Remote system error)
May 9 18:24:10 m2001 last message repeated 1 time
May 9 18:24:10 m2001 automountd[428]: [ID 834250 daemon.error] Mount of c-store2:/data2 on /data/rw10: I/O error
The load is not heavy by my standards as there are only 50 concurrent clients trying to mount that file space and the
same clients are mounting the thumper and do not get this problem.
I have had considerably heavier loads on the linux based nfs3 servers when 300 concurrent jobs were accessing one
file space at a time and I did not get this problem.
Have any of you seen this and found a remedy. any hints would be welcome
