NFS access failed for server xxx error 7 (RPC: Authentication error)

Hi Guru,

We are facing problem while NFS mounting between ruprddb(CLuster node) to ruleccdev system. Details are as below.

Server:ruprddb ( Cluster name – dbciRRP )
Client:ruleccdev
OS: HPUX 11.31
NFS : A.11.31.07

From server ruprddb file system

dbciRRP:/export/usr/sap/trans /usr/sap/trans

if I set the entry in /etc/dfs/dfstab
share -F nfs -o rw=ruleccdev,access=ruleccdev /usr/sap/trans

bdf showing below error
dbciRRP:/export/usr/sap/RRP
10420224 3876585 6134811 39% /usr/sap/RRP
dbciRRP:/export/sapmnt/RRP
10420224 3940872 6074866 39% /sapmnt/RRP
NFS access failed for server dbciRRP: error 7 (RPC: Authentication error)
NFS fsstat failed for server dbciRRP: error 7 (RPC: Authentication error)
bdf: /usr/sap/trans: Permission denied

Highly appreciate, if you could suggest the solution on priority.


Thanks in advance

Prashant

Re: NFS access failed for server xxx error 7 (RPC: Authentication error)

try to use the node name instead of cluster name.

Shalom,

Correct permission on the NFS server. Restart all three nfs services in this way.

/sbin/init.d/nfs.client stop
/sbin/init.d/nfs.server stop
/sbin/init.d/nfs.core stop

/sbin/init.d/nfs.core start
/sbin/init.d/nfs.server start
/sbin/init.d/nfs.client start

Try again your remote mount command.

Also, please post.
showmount -e hostname

Run that command from both the server and remote system.
