Using Ceph-Ansible stable-4.0 I did a rolling update from latest Mimic to Nautilus 14.2.2 on a cluster yesterday, and the update ran to completion successfully.

However, in ceph status I see a warning of the form "Legacy BlueStore stats reporting detected” for all OSDs in the cluster.

Can anyone help me with what has gone wrong, and what should be done to fix it?

I thin you should start to run repair for your OSD's - [1]

Thanks Konstantin - running the BlueStore repair as indicated appears to be working.

One difference from Sage’s description of the scenario is that I did not explicitly create new OSDs during or after the Nautilus upgrade. Perhaps the Ceph-Ansible rolling update script did something to trigger this.

the known bug is that stats will show up incorrectly; the warning is expected after the upgrade
