Jonas, could you please run "ceph-bluestore-tool --path <osd path> --allocator block --command free-dump" and share the output... Thanks, Igor On 12/12/2020 10:27 PM, Igor Fedotov wrote:
Hi Jonas,
didn't you try to switch your OSDs back to bitmap allocator as per my comment #6 in the tracker?
Also please set debug-bluestore to 20 and collect the startup log for the failing OSD - since it's repeatedly failing on exactly the same assertion this would be very helpful. That's the info I've been lacking since the initial occurrence.
Thanks,
Igor

Hi!
Yesterday a third OSD died with a failed assertion, and it can no longer boot. It's the third OSD within 11 days.
There's already a tracker issue:https://tracker.ceph.com/issues/48276

When the OSD tries to boot (now with 14.2.15), it fails again:

Anyone else with these symptoms? Any ideas how we can track it down?
