Common

The following checks indiciate general issues with the cluster that are not specific to any daemon type.

Warnings

WCOM1

A running OSD and MON daemon were detected in the same node. Colocating OSDs and MONs is highly discouraged.

Errors

ECOM1

A ceph configuration file cannot be found at /etc/ceph/$cluster-name.conf.

ECOM2

The ceph executable was not found.

ECOM3

The /var/lib/ceph directory does not exist or could not be collected.

ECOM4

The /var/lib/ceph directory was not owned by the ceph user.

ECOM5

The fsid defined in the configuration differs from other nodes in the cluster. The fsid must be the same for all nodes in the cluster.

ECOM6

The installed version of ceph is not the same for all nodes in the cluster. The ceph version should be the same for all nodes in the cluster.

ECOM7

The installed version of ceph is not the same as the one of a running ceph daemon. The installed ceph version should be the same as all running ceph daemons. If they do not match, the daemons most likely have not been restarted correctly after a version change.

ECOM8

The fsid field must exist in the configuration for each node.

ECOM9

A cluster should not have running daemons with a cluster fsid that is different from the rest of the daemons in a cluster. This potentially means that different cluster identifiers are being used, and that should not be the case.

ECOM10

Only a single monitor daemon shuld be running per host, having more than one monitor running on the same host reduces a cluster’s resilience if the node goes down.
