Following a reboot of an NFS server, client machines are unable to mount it, returning the message"mount: RPC: Timed out"

  • I've ruled out iptables rules by clearing them
  • /etc/exports on the server is unchanged
  • rpcinfo -p from the client to the server looks OK:
    program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper

    100024    1   udp  32765  status
    100024    1   tcp  32765  status

Advice for further diagnostics much appreciated!

I resolved this by restarting some of the client side components with

/etc/init.d/nfs-common restart

I was then able to mount the filesystem just fine. Phew ;)

    This script does not exist on SuSE, Fedora, Centos (and by extension is Redhat). – mdpc Aug 17 '11 at 22:39

You need to make sure that both the client and the server have a working portmap service, visible from the client. It's possible that you don't have a working portmap on the client.
