Hello,
given small test cluster, following sequence resulted to the inability
to join back for freshly formatted OSD:
- update cluster sequentially from cuttlefish to dumpling to firefly,
- execute tunables change, wait for recovery completion,
- shut down single osd, reformat filestore and journal,
- start it back (auth caps and key remained the same).
Version is 5a10b95f7968ecac1f2af4abf9fb91347a290544. Any ideas why
this may happen are very welcomed. I suspect some resource starting
from 29499 (probably earlier but this line doing a clear separation
between init stage and loop in the log) line in strace which is
continuously asking for resource all way down may be a root cause
(something just after journal and collections initialization) but I
have no idea what it may be.
Thanks!

Can you send us your ceph.conf (edit away any sensitive information you
may have), the log for the osd you are having trouble with (with 'debug
monc = 10' and 'debug ms = 1'), and the log for your monitors (with
'debug mon = 10', 'debug ms = 1')?
