MDS Autoscaler Module
|
|
=====================
|
|
|
|
The MDS Autoscaler Module monitors file systems to ensure sufficient MDS
|
|
daemons are available. It works by adjusting the placement specification for
|
|
the orchestrator backend of the MDS service. To enable, use:
|
|
|
|
.. sh:
|
|
|
|
ceph mgr module enable mds_autoscaler
|
|
|
|
The module will monitor the following file system settings to inform
|
|
placement count adjustments:
|
|
|
|
- ``max_mds`` file system setting
|
|
- ``standby_count_wanted`` file system setting
|
|
|
|
The Ceph monitor daemons are still responsible for promoting or stopping MDS
|
|
according to these settings. The ``mds_autoscaler`` simply adjusts the
|
|
number of MDS which are spawned by the orchestrator.
|
|
|
|
.. note: There is no CLI or module configurations as of now. Enable or disable
|
|
the module to turn on or off.
