[Gluster-users] Unable to start nfs server

[David Coulson]

Yep.

[root at dresproddns01 ~]# service glusterd stop
Stopping glusterd:                                         [  OK  ]
[root at dresproddns01 ~]# ps ax | grep nfs
  120494 pts/0    S+     0:00 grep nfs
2167119 ?        S      0:00 [nfsiod]
[root at dresproddns01 ~]# service rpcbind stop
Stopping rpcbind:                                          [  OK  ]
[root at dresproddns01 ~]# rpcinfo -p
rpcinfo: can't contact portmapper: RPC: Remote system error - No such 
file or directory
[root at dresproddns01 ~]# service rpcbind start

[root at dresproddns01 ~]# service glusterd start
Starting glusterd:                                         [  OK  ]
[root at dresproddns01 ~]# rpcinfo -p
    program vers proto   port  service
     100000    4   tcp    111  portmapper
     100000    3   tcp    111  portmapper
     100000    2   tcp    111  portmapper
     100000    4   udp    111  portmapper
     100000    3   udp    111  portmapper
     100000    2   udp    111  portmapper

Note that I waited a short while between the last two steps. FYI, this 
is RHEL6 (the two systems that work are RHEL6 too, so I'm not sure it 
matters much).
