Hi Eugen,
try deploying the NFS service like this:
https://docs.ceph.com/en/latest/mgr/nfs/
Some had only success deploying it via the dashboard.
Best,
Malte

Hi,
I'm re-evaluating NFS again, testing on a virtual cluster with 18.2.4.
For now, I don't need haproxy so I use "keepalive_only: true" as
described in the docs [0]. I first create the ingress service, wait for
it to start, then create the nfs cluster. I've added the specs at the
bottom.
I can mount the export with the virtual ip. Then I just shut down the VM
where the nfs service was running, the orchestrator successfully starts
a nfs daemon elsewhere, but the keepalive daemon is not failed over. So
mounting or accessing the export is impossible, of course. And after I
power up the offline host again, nothing is "repaired", keepalive and
nfs run on different servers until I intervene manually. This doesn't
seem to work as expected, is this a known issue (couldn't find anything
on tracker)? I have my doubts, but maybe it works better with haproxy?
Or am I missing something in my configuration?
I haven't tried with a newer release yet. I'd appreciate any comments.
Thanks,
Eugen
