Description Francesco Pantano 2021-04-29 07:49:48 UTC

Description of problem:

The cephadm generated ganesha.conf differs from what manila uses because there's no flexibility in configuring different options other than [1].
The Openstack ganesha config used for manila was generated by ceph-ansible through [2].
The ganesha config produced by the nfs cephadm deployed daemon breaks the backward compatibility with the ceph-ansible generated one.
For this reason, even though bug [3] is solved, we won't still be able to properly configure the Manila project with Ceph.

moving past 5.1. I'd like to have Dimitri back, before looking into this.
