Fixed In Version: ceph-18.2.1-237.el9cp
Doc Type: Bug Fix
Doc Text:
.Monitors no longer get stuck in elections during crash/shutdown tests Previously, the `disallowed_leaders` attribute of the MonitorMap was conditionally filled only when entering `stretch_mode`. However, there were instances wherein Monitors that just got revived would not enter `stretch_mode` right away because they would be in a `probing` state. This led to a mismatch in the `disallowed_leaders` set between the monitors across the cluster. Due to this, Monitors would fail to elect a leader, and the election would be stuck, resulting in Ceph being unresponsive. With this fix, Monitors do not have to be in `stretch_mode` to fill the `disallowed_leaders` attribute. Monitors no longer get stuck in elections during crash/shutdown tests.
