I just wanted to follow up on this issue as it corrected itself today. I started a drain/remove on two hosts a few weeks back, after the rolling restart of mgr/mon on the cluster it seems that the ops queue either became locked or overwhelmed with requests. I had a degraded PG during the rolling reboot of the mon/mgr and that seems to have blocked ceph orch, balancer, autoscale-status cli commands from returning. I could see in the manager debug logs that balancer was indeed running and returning results internally from the internal scheduled process but the cli would hang indefinitely. This morning the last degraded/offline PG got resolved and all commands are running again.
Moving forward is there a method to view the ops queue or monitor if the queue gets full and starts to deprioritize CLI commands?
