Naresh,

Did you get a solution to this in the end?

I'm having the same issue, just using the vfs FSAL

Ganesha 2.6.1

/var/log/messages filled with:

Sep 18 21:51:33 fsrv01 rpc.statd[2545]: SM_MON/SM_UNMON call from non-local host ::1
Sep 18 21:51:33 fsrv01 rpc.statd[2545]: STAT_FAIL to pclhhfsrv01 for SM_MON of ::ffff:10.10.10.220

Ganesha log filled with:

18/09/2018 21:51:33 : epoch 5ba09ee4 : fsrv01 : ganesha.nfsd-23030[svc_206] nsm_monitor :NLM :CRIT :Monitor ::ffff:10.10.10.220 SM_MON failed (1)

I -can- ping ::ffff:10.10.10.220

I did try running with some clients accessing home directories but eventually I got:

17/09/2018 15:06:27 : epoch 5b9fb130 : fsrv01 : ganesha.nfsd-4072[svc_24] nsm_monitor :NLM :CRIT :Monitor ::ffff:10.10.10.240 SM_MON failed: RPC: Timed out

Then I just go a load of "vfs_lookup_path :FSAL :CRIT :Could not open directory for path" until I restarted ganesha

Any assistance would be much appreciated

Thanks

David

Oh, it looks like rpc.statd is refusing the connection because it
doesn't think ::1 (the IPv6 localhost address) is localhost.  If so,
this would be either a bug or a misconfiguration in rpc.statd.
