Too large for pastebin.. The problem is continually crashing new OSDs. Here is the latest one.

could you please set debug bluestore to 20 and collect startup log for this specific OSD once again?

I restarted most of the OSDs with the stupid allocator (6 of them wouldn't start unless bitmap allocator was set), but I'm still seeing issues with OSDs crashing. Interestingly it seems that the dying OSDs are always working on a pg from the .rgw.meta pool when they crash.

Hi Brett,
in Nautilus you can do that via
ceph config set osd.N bluestore_allocator stupid
ceph config set osd.N bluefs_allocator stupid
See https://ceph.com/community/new-mimic-centralized-configuration-management/ for more details on a new way of configuration options setting.
A known issue with Stupid allocator is gradual write request latency increase (occurred within several days after OSD restart). Seldom observed though. There were some posts about that behavior in the mail list this year.
Thanks,
Igor.

I'll give that a try. Is it something like...ceph tell 'osd.*' bluestore_allocator stupidceph tell 'osd.*' bluefs_allocator stupid
And should I expect any issues doing this?

I should read call stack more carefully... It's not about lacking free space - this is rather the bug from this ticket:
http://tracker.ceph.com/issues/40080
You should upgrade to v14.2.2 (once it's available) or temporarily switch to stupid allocator as a workaround.
Thanks,
Igor

Hi Brett,
looks like BlueStore is unable to allocate additional space for BlueFS at main device. It's either lacking free space or it's too fragmented...
Would you share osd log, please?
Also please run "ceph-bluestore-tool --path <substitute with path-to-osd!!!> bluefs-bdev-sizes" and share the output.
Thanks,
Igor
