Parameters and roles

The Add monitor host plugin parameters are mostly the same as the ones for the Deploy Ceph cluster plugin. However, the plugin has the following role:

mons

Defines the nodes to deploy monitors.

Also, there is a limitation on deployment: for consistency and problem avoidance, Decapod checks version it is going to install. If cluster has inconsistent versions, deployment is stopped: user has to fix versions within a cluster. If version user is going to deploy is newer than installed ones, process is also failing: user has to update cluster packages first.

There are 2 parameters responsible for that:

ceph_version_verify This is a boolean setting which checks that strict mode is enabled. Otherwise (it is set to false) no verification described above is done.

ceph_version_verify_packagename The name of the package to check. Usually, you do not need to touch this setting at all.
