Bara,

The exact name of the service is "nfs-server". In your description on this bug, everywhere you say "nfs-service" should be "nfs-server".

Why was nfs-server running in the first place?
Looks like a system misconfiguration to me.

Comment 8 Alfredo Deza 2018-03-16 11:23:53 UTC

I get that this might be a system misconfiguration, but why wouldn't ceph-ansible be able to stop the service if it is running in order to continue the installation?

Comment 10 Sébastien Han 2018-03-21 07:46:29 UTC

Ok, so this sounds more like a request.
I didn't get that this was on purpose.
I guess we can if the service runs and stop it/disable it.

However, I'm just really hesitant changing the system configuration, if kNFS is running it might be for a good reason.

The best thing we should do IMHO is to check if the service runs, fail the playbook and ask to stop it before pursuing the installation.

Is that acceptable to everyone?
Thanks

Hi leseb,

When we do the manual way of installing nfs-ganesha, it is mandatory to stop and disable kNFS before installing nfs-ganesha-rgw. NFS-Ganesha will not start if another NFS instance is running.  

As per the doc:
" If the nfs-service service is running, stop and disable it:
# systemctl stop nfs-server.service
# systemctl disable nfs-server.service "

As we are automating nfs-ganesha-rgw installation in 3.0, it will be better to stop and disable nfs-server.service via ceph-ansible. 

Thanks,
Vidushi

Here is a PR that stops the service before the nfs-ganesha service can be started:

https://github.com/ceph/ceph-ansible/pull/2488

Comment 13 Ali Maredia 2018-04-12 18:27:32 UTC

The above PR has been merged. Ceph-ansible now stops nfs-server via systemd if before it start nfs-ganesha.

Comment 28 Ameena Suhani S H 2019-10-15 11:06:04 UTC

Verified using ceph-ansible-3.2.29-1.el7cp.noarch.

Moving to VERIFIED state.
