Sridhar Seshasayee 2020-09-09 07:52:15 UTC Doc Text Cause:
A prior enhancement to auto-tune the memory used by a
monitor included only the leader monitor.

Consequence:
The follower monitors can use up more memory than their set
memory target and potentially go down once the memory is
exhausted.

Fix:
Auto-tune the memory for all monitors (leader and
followers).

Result:
All the monitors continuously tune their allocated memory
and ensure memory is not exhausted.

.Ceph Monitors can grow beyond the memory target

Auto-tuning the memory target was only done on the Ceph Monitor leader and not the Ceph Monitors following the leader. This was causing the Ceph Monitor followers to exceed the set memory target, resulting in the Ceph Monitors crashing once its memory was exhausted. With this release, the auto-tuning process applies the memory target for the Ceph Monitor leader and its followers so memory is not exhausted on the system.
