It is sometimes helpful to query the :Ref:`Store` component to ask about the health of the Ceph cluster.
To do this, log into any machine running a store-monitor or store-daemon service. Then,
nse deis-store-monitor or nse deis-store-daemon and issue a ceph -s. This should output the
health of the cluster like:
cluster 6506db0c-9eae-4bb6-a40a-95954dd3c4c3
health HEALTH_OK
monmap e3: 3 mons at {deis-1=172.17.8.100:6789/0,deis-2=172.17.8.101:6789/0,deis-3=172.17.8.102:6789/0}, election epoch 8, quorum 0,1,2 deis-1,deis-2,deis-3
osdmap e7: 3 osds: 3 up, 3 in
pgmap v14: 192 pgs, 3 pools, 0 bytes data, 0 objects
19378 MB used, 28944 MB / 49200 MB avail
192 active+cleanIf you see HEALTH_OK, this means everything is working as it should.
Note also monmap e3: 3 mons at... which means all three monitor containers are up and responding,
and osdmap e7: 3 osds: 3 up, 3 in which means all three daemon containers are up and running.
We can also see from the pgmap that we have 192 placement groups, all of which are active+clean.

There are two classes of Deis users: normal users and administrators.
- Users can use most of the features of Deis - creating and deploying applications, adding/removing domains, etc.
- Administrators can perform all the actions that users can, but they can also create, edit, and destroy clusters.
The first user created on a Deis installation is automatically an administrator.
You can use the deis perms command to promote a user to an administrator:
$ deis perms:create john --admin
