We are running tons of Ceph clusters on Luminous with bluefs_allocator being
bitmap, and when looking at Nautilus, 14.1.22, bluefs_allocator is now

Hi Frank,
I'd be interested to read that paper, if you can find it again. I
don't understand why the volatile cache + fsync might be dangerous due
to a buggy firmware, but yet we should trust that a firmware respects
FUA when the volatile cache is disabled.

Hi Dan,
I can try to find the thread and the link again. I should mention that my inbox
is a mess and our search function on the outlook 365 app is, well, don't
mention the war. Is there a "list by thread" option on the lists.ceph.io? I can
go through threads for 2 years, but not all messages.
