NFS Mount Problem

[Nagu SR]

Hi,

Both client and server--HP-UX 11.31-NFS 3

We had hard mounted one filesystem which is not accessible now. any command related to NFS is not working. `bdf` says /FILESYS is not responding. We had tried options (Only in Client) like umount (Doesnt work) restarted NFS services like `nfs.server`; autofs; nfs.client; lockmgr; nfs.core but still problem persists.
I had been to somany NFS threads in ITRC, but most of the sites had given me hope that the NFS issues are addressed in 11.31. If so, is there any way other than reboot??

NFS Patch-- B.11.31;
And we are able to mount the NFS server's exported filesys in other clients.(same OS-NFS patch level) Problem is only in one client.


Can someone help me please???

Hi
I assume that the server 11.31 acting as the NFS server has only one client.
apart from trying the restart of the NFS services on the client, can you try unexporting the Filesystem and if not much impact on the server restarting the NFS services and reexporting them then mount on the client?

#showmount -e

is this command showing proper output ?

[Avinash20]

So it only the NFS client which is having the issue

Could you post the output of below command from NFS client.

# rpcinfo -p
# rpcinfo -p

Hi,

I cant do the restart of NFS service in NFS server as it would have major Prod Impact.

The Output of the command
`rpcinfo -p servername`

showmount -e servername

export list for servername:
/oradump (everyone)
/var/opt/ignite/clients (everyone)


I had problem in accessing /oradump. now when I tried mouonting other Filesys (/var/opt/ignite/clients) I'm not able to mount it as well. I even tried mounting different servers NFS volumes here but it failed. So problem is with only client

Thx

Hi,

We had to reboot the NFS client to fix the issue.

However, we have updated NFS version to ONCplus version B.11.31.06 as suggested by HP.
