Ceph

While attempting to trigger a monitor bug, triggered this instead.

Unfortunately, both the machine state and the osd logs were lost as I assumed I had finally triggered said monitor bug.

Triggered once in 55 runs using the following job yaml. Also, attaching teuthology log as that's the only thing (aside from the mon logs) that has survived.
