Description

Hello,

We have been unable to use the local prediction model for many years. Our first attempt was on the Nautilus version, and the most recent attempt was on Quincy, but both were unsuccessful. There is likely an issue with the device health module, as the self-test reports the following.

Ceph version 16.2.10 (Pacific)

ceph mgr self-test module devicehealth
Error EPERM: Test failed: Remote method threw exception: Traceback (most recent call last):
File "/usr/share/ceph/mgr/devicehealth/module.py", line 233, in self_test
assert r 0
AssertionError

Ceph version 17.2.5 (Quincy)

ceph mgr self-test module devicehealth
Error EPERM: Test failed: Remote method threw exception: Traceback (most recent call last):
File "/usr/share/ceph/mgr/devicehealth/module.py", line 258, in self_test
assert r 0
AssertionError

Regards,
Michal Strnad
