problems with NFS mount

[holdahl]

I'm trying to mount a filesystem on some new AIX servers.
The filesystem is located on one of the old servers:

root@server1:/# mount server2:/imagefs /mnt
nfsmnthelp: 1831-019 server2: System call error number -1.

mount: 1831-008 giving up on:
server2:/imagefs
System call error number -1.

Anyone seen this problem?

The server I'm having trouble with is part of a HACMP cluster.

Try on the client running:

rpcinfo -p <server_ip>
showmount -e <server_ip>

Sounds like the export permissions are wrong. Also, most NFS mount problems are down to resolving IPs. Make absolutely sure that your client and its IP is resolvable in both directions.

what say´s the lssrc -g nfs output?
is lookup a hostname from an IP address and reverse IP address from the hostname ok?

Found the problem.

The NFS server was not able to resolve all IPs.
Solved it by adding those to /etc/hosts

Mounting works fine now.

Thanks for all suggestions.
