Ceph-proxy unable to relate to ceph-fs

[Fulvio Galeazzi]

Extend charm-ceph-proxy code so it can relate to ceph-fs.

Ceph-proxy charm is useful in those cases where you have an existing Ceph cluster you want to use for Cinder/Rados/whatever, and for a number of reasons you cannot have Ceph managed via charms.

Current charm-ceph-proxy works to relate with Cinder and Rados, but unfortunately is lacking capability to relate to Ceph-FS (and thus, it
prevents adding Manila).

The proposed patch adds a ceph-proxy:mds interface and the relevant code, to make it possible to establish a relation with ceph-fs:ceph-mds.

I think this is a wishlist item, but it's a bit hard to tell. Please could you clarify your bug (by editing the description) to:

1. What is requirement that is not being met; i.e. the scenario that the current set of charms don't have the feature set to solve?
2. What you think may solve this problem.

Many thanks

Right Alex, apologies for being cryptic.

Please let me know whether it's more clear now.

Thanks!

Hallo all, just a quick comment to let you know that previous
review was not properly creating Ceph user.
The new review:
https://review.opendev.org/c/openstack/charm-ceph-proxy/+/784212
 now includes code that is actually working, as verified in my
environment. :-) Ceph user gets created, mds service on ceph-fs
stays alive.
Thanks!

Fulvio

    Add support for CephFS.

    Extend ceph-proxy to implement ceph-mds interface, this allows the
    ceph-fs to be related. The testing is made reusing the CephFSTests
    testing class.

    Usage example:

      juju add-relation ceph-proxy:mds ceph-fs:ceph-mds
