NFS mount problem on HP Cluster from linux NFS server.
I have HP Cluster 11.31 client and Linux SUSE 11 NFS server.
Using /etc/auto.direct and restarting /sbin/init.d/autofs on client then cd into directory I get long wait
then doing ls first time I get after long wait:
NFS readdirplus failed for server panwppnpd: error 5 (RPC: Timed out)
Second ls shows files. As long as it is mounted I can see the files. If automounter unmounts it
and I try to again, I get same problem.
This problem is only with HP Clusters. Other non HP Clusters mount the same export from Linux NFS server okay.
Have not found anything to resolve this problem.
P.S. This thread has been moved from HP-UX>System Administration to HP-UX > networking. -HP Forum Moderator

Re: NFS mount problem on HP Cluster from linux NFS server.
Posting the AutoFS maps would help. Do you get the same behavior when you manually mount the exact same filesystem from the exact same server using the exact same options?

Re: NFS mount problem on HP Cluster from linux NFS server.
Linux panwppnpd 3.0.58-0.6.6-default NFS server /etc/exports file entry:
/usr/sap/trans *(rw,sync,no_root_squash,no_subtree_check)
# exportfs
/usr/sap/trans <world>
HP Cluster /etc/auto.direct:
/usr/sap/trans panwppnpd:/usr/sap/trans
This only happens when using automounter on HP clusters.
If I manually mount it. It is okay.

Re: NFS mount problem on HP Cluster from linux NFS server.
Please mount the filesystem manually on the HP-UX client and then post the output of "nfsstat -m" so I can see which mount options are used.

Re: NFS mount problem on HP Cluster from linux NFS server.
Its already vers=3 from above.
I remounted with automounter again and here is the nfsstat.
/usr/sap/trans from panwppnpd:/usr/sap/trans

Reads: srtt=8 (20ms), dev=8 (40ms), cur=5 (100ms)
