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.
