[CentOS] Help needed with NFS issue

[Steve Thompson]

Interesting. It looks like some kind of RPC failure. During the hang, I 
cannot contact the nfs service via RPC:

# rpcinfo -t <server> nfs
rpcinfo: RPC: Timed out
program 100003 version 0 is not available

even though it is supposedly available:

# rpcinfo -p <server>
    program vers proto   port
     100000    2   tcp    111  portmapper
     100000    2   udp    111  portmapper
     100024    1   udp   1007  status
     100024    1   tcp   1010  status
     100021    1   udp  35077  nlockmgr
     100021    3   udp  35077  nlockmgr
     100021    4   udp  35077  nlockmgr
     100021    1   tcp  56622  nlockmgr
     100021    3   tcp  56622  nlockmgr
     100021    4   tcp  56622  nlockmgr
     100011    1   udp   1009  rquotad
     100011    2   udp   1009  rquotad
     100011    1   tcp   1012  rquotad
     100011    2   tcp   1012  rquotad
     100003    2   udp   2049  nfs
     100003    3   udp   2049  nfs
     100003    4   udp   2049  nfs
     100003    2   tcp   2049  nfs
     100003    3   tcp   2049  nfs
     100003    4   tcp   2049  nfs
     100005    1   udp    605  mountd
     100005    1   tcp    608  mountd
     100005    2   udp    605  mountd
     100005    2   tcp    608  mountd
     100005    3   udp    605  mountd
     100005    3   tcp    608  mountd

However, I can connect to the service via telnet:

# telnet <server> nfs
Trying <ipaddr>...
Connected to <server> (<ipaddr>).
Escape character is '^]'.

so the service is running but internally borked in some way.
