om <path> purge
This command asks the cluster to orchestrate a stop, unprovision and delete. Non-leader instances are sequenced first.
Purging a service does not purge its referenced volumes.
Purging a volume actually removes all volume data.
om <path> delete
This command does not stop nor unprovision the object, so it can leave unreferenced mounts, containers and processes on the nodes.
This command should be used by administrators only.
