Bug Description

While enabling Ceph RadosGW on Bionic/Ussuri I have run into intermittent failures which appear to be caused by the PG autoscaler.

HEALTH_ERR Module 'pg_autoscaler' has failed: division by zero

It has recently been fixed upstream [0][1] and I do not think we have this in our packages.

This fix was included in the 5.2.0 release on the 23rd March - so will be included in my upload for that to Focal development. Closing this bug as covered elsewhere.

I'm seeing this on the latest Ubuntu 20.04.1, fully upgraded.

Ceph version 15.2.3-0ubuntu0.20.04.2.

The `ceph status` is "HEALTH_ERR", Module 'pg_autoscaler' has failed: division by zero, 1 daemons have recently crashed.
