What distribution and kernel are you running?
I recently found my cluster running the 3.10 centos kernel when I thought it was running the elrepo kernel. After forcing it to boot correctly, my flapping osd issue went away.

Hi,
we are experiencing massive problems with our Ceph setup. After starting
a "repair pg" because of scrub errors OSDs started to crash, which we
could not stop so far. We are running Ceph 12.2.4. Crashed OSDs are both
bluestore and filestore.
Our cluster currently looks like this:

The last OSDs that crashed are #28 and #36. Please find the
corresponding log files here:
http://af.janno.io/ceph/ceph-osd.28.log.1.gz
http://af.janno.io/ceph/ceph-osd.36.log.1.gz
The backtraces look almost the same for all crashed OSDs.
Any help, hint or advice would really be appreciated. Please let me know
if you need any further information.
Best Regards
