No role for rbd-client (e.g. mapping images)

[johanneskastl]

Description of Issue/Question

There are several roles available for the various clients. But I found none that would fit for a client that wants to e.g. map a rbd image.

I can interact with rbd from the master/admin node, i.e. create images, list pools, but when trying to map an image (as described in the SES201 training) I get a missing kernel module. Of course I can prepare the client manually, but it would be nice if there were a role doing that for me.

Is there none? I doubt that this included in one of the client roles I have:

role-client-cephfs
role-client-iscsi
role-client-nfs
role-client-radosgw

I just set up another cluster using SES5 (SLES12 SP3), and there mapping works out of the box on the admin/master node. Not sure if it is intended behaviour to no longer have this working in SES6, so the client-role might still be a handy addition...
