NFS problem - RPC bind failure

[Adam Noble]

Hi,

I have a problem which I just don't understand. We have a server that crashed. On re-boot the NFS services failed to mount two filesystems via NFS. I was not totally surprised as I'd seen this behaviour before. I was getting rpcbind failures. Anyway after reboot I checked and I could do a basic NFS mount however not the directories I wanted to as was getting permission denied. I looked on the server where the filesystems were locally mounted and could see they were exported with the options -root=myserver -access=myserver. Once I removed these options i was able to mount them. I assumed it was therefore an issue with resolving the hostname (of myserver) to IP that was causing the problem. The hostfile is correct however and if I do an nslookup I see what I expect. NFS never fails to surprise me or cause me pain but this one appears to defy logic. Any ideas?

What is the info for hosts: in /etc/nsswitch.conf?

The file does not exist.

Hi Adam,

Does the server trying to mount the remote filesystems have multiple network interfaces configured? It could be trying to mount using the wrong interface. Also on the remote server did you have the fully qualified hostname. See man exports and look under the option for access=
