fsid:
uuid specific to a ceph cluster used to ensure that different
clusters don't get mixed up - use `uuid` to generate one.
monitor-secret:
a ceph generated key used by the daemons that manage to cluster
to control security. You can use the ceph-authtool command to
generate one:
ceph-authtool /dev/stdout --name=mon. --gen-key
These two pieces of configuration must NOT be changed post bootstrap; attempting
todo this will cause a reconfiguration error and new service units will not join
the existing ceph cluster.
The charm also supports specification of the storage devices to use in the ceph
cluster.
osd-devices:
A list of devices that the charm will attempt to detect, initialise and
activate as ceph storage.
This this can be a superset of the actual storage devices presented to
each service unit and can be changed post ceph bootstrap using `juju set`.
At a minimum you must provide a juju config file during initial deployment
