Hi,
we decided to test a bit the upcoming ceph release (luminous). It seems
that I need to install this ceph-mgr daemon as well. But I don't
understand exactly why I need this service and what I can do with it.
The ceph Cluster is working well without installing any manager daemon.
However in the ceph status output there is a health error ("no active
mgr")
My questions:
Can we run the cluster without this additional daemon? If yes, is it
possible to supress this health error?
What exactly is the purpose of this service. The documentation oncontains
very rare information about it.
Regards
Manuel
