Hi David,

I tried disabling IPv6, but, that didn't help. I cannot pinpoint a change that resolved the issue. There are no changes in NLM between 2.6.2 and 2.6.3. So, there is something else that helped solve this issue.

Thanks, Naresh. I may not be able to upgrade to 2.6.3 for a while as I'm using the packages in the Ceph repos, latest is 2.6.2.

I had a quick look through the commits for 2.6.3 and couldn't find reference to this particular issue. Can you point me in the direction of some more info please? Any idea how to workaround this issue on CentOS 7.5? I did try creating /etc/gai.conf but didn't seem to have any effect.

Upgrade to 2.6.3 fixed the issue. rpc.statd works with only IPv4 localhost address.

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.
