Fixed In Version: ceph-17.2.6-159.el9cp
Doc Type: Bug Fix
Doc Text:
Cause: The `disallowed_leaders` attribute of the MonitorMap is conditionally filled only when we can enter `stretch_mode`, however, there is an instance where Monitors that just got revived will not be able to enter `stretch_mode` right away because it is in a `probing` state. Therefore, this leads to a mismatch in the `disallowed_leaders` set between the monitors across the cluster. Consequence: Monitors fail to elect a leader, the election gets stuck and Ceph becomes unresponsive. Fix: Monitors don't have to be in stretch_mode to fill the `disallowed_leaders` attribute. Result: Monitors don't get stuck in elections during crash/shutdown tests.
