MGR_DOWN
________
All manager daemons are currently down. The cluster should normally
have at least one running manager (``ceph-mgr``) daemon. If no
manager daemon is running, the cluster's ability to monitor itself will
be compromised, and parts of the management API will become
unavailable (for example, the dashboard will not work, and most CLI
commands that report metrics or runtime state will block). However,
the cluster will still be able to perform all IO operations and
recover from failures.
The down manager daemon should generally be restarted as soon as
possible to ensure that the cluster can be monitored (e.g., so that
the ``ceph -s`` information is up to date, and/or metrics can be
scraped by Prometheus).
