unable to start nfs daemon on a server.

Hi All,

We can not start NFS service even we run " service nfs start" .
At a glance, the command goes well but no nfs proc is running on a server.

[root]# service nfs start

[root]# --- no message so far so I guess the command had no error.

When we stop the service, we got massage as follows,

[root]# service nfs stop
Shutting down NFS mountd: [FAILED]
Shutting down NFS daemon: [FAILED]
Shutting down NFS quotas: [FAILED]

[root]# service nfs status
rpc.mountd is stopped
nfsd is stopped
rpc.rquotad is stopped

[root]# rpcinfo -p 127.0.0.1
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper

We already tried to reboot server but it did not solve the problem.

[additional info]
We checked "pstree" and found that some rpc.* proc are running on normal server comparred with the server.

rpc.idmapd
rpc.mountd
rpc.rquotad
rpc.statd

We want to start NFS service on the server.
Please give us advice.

Regads,
Daisuke
