| * **Dont tweak max_mds** Modifying the FS setting variable ``max_mds`` is | ||
| sometimes perceived as a good step during troubleshooting or recovery effort. | ||
| Instead, doing so might further destabilize the cluster. If ``max_mds`` must | ||
| be changed in such circumstances, run the command to change ``max_mds`` with | ||
| the confirmation flag (``--yes-i-really-mean-it``) | ||
|
|
||
| .. _pause-purge-threads: | ||
| * **Turn off async purge threads** The volumes plugin spawns threads for | ||
| asynchronously purging trashed/deleted subvolumes. To help troubleshooting or | ||
| recovery effort, these purge threads can be disabled using: | ||
|
|
||
| .. code:: bash | ||
|
|
||
| ceph config set mgr mgr/volumes/pause_purging true | ||
|
|
||
| To resume purging run:: | ||
|
|
||
| ceph config set mgr mgr/volumes/pause_purging false | ||
|
|
||
| .. _pause-clone-threads: | ||
| * **Turn off async cloner threads** The volumes plugin spawns threads for | ||
| asynchronously cloning subvolume snapshots. To help troubleshooting or | ||
| recovery effort, these cloner threads can be disabled using: | ||
|
|
