Description

The Sepia LRC's mgr keeps throwing the following error:

2022-05-11T13:44:10.636+0000 7fdb9d799700  0 [pg_autoscaler ERROR root] pool 119 has overlapping roots: {-5, -1}
2022-05-11T13:44:10.640+0000 7fdb9d799700  0 [pg_autoscaler ERROR root] pool 121 has overlapping roots: {-40, -5, -1}
  1. This error message is buried in a mgr log. It should be a ceph health error if it truly is an error.
  2. The error message just dumps the pool ID. I have no idea how to extrapolate the pool name from the ID #.
  3. I have no idea how to fix this. The autoscaler's just stuck. I think the error message should include a link to documentation on how to resolve.

This is all I could find and I don't think it's applicable to our situation: https://forum.proxmox.com/threads/ceph-overlapping-roots.104199/

This isn't an error, just an indication that the autoscaler won't scale PGs due to this. Also came up here https://www.spinics.net/lists/ceph-users/msg68579.html. Let's change this to a warning.
