Ceph » mgr

Description of problem¶

Since we updated to v16.2.5 (using cephadm since availability) we see this status message :-(

MGR_MODULE_ERROR: Module 'devicehealth' has failed: can't subtract offset-naive and offset-aware datetimes

ceph device get-health-metrics <devid>

also gives a similar message ...

We assume that the failure prediction does also not work anymore too ....

Environment¶

• Platform (OS/distro/release): Ubuntu 20.04.3 LTS
