Description
Log is attached. 3 of my 4 OSDs have crashed in a similar manner at different times. I'm running Ceph on a single node for testing. I have 4, 8TB OSDs running BlueStore with dm-crypt, 1 mgr, 1 mds and 1 mon. The machine is running Arch Linux and Ceph has been built from the source release. I have a 2/1 EC pool with 256 pgs for data and a size 2 replicated pool with 256 pgs for metadata. The only client was a single instance of rsync.

- Status changed from New to Duplicate
It is hard to tell because the lines preceding the snippet are missing, but I'm pretty sure this is a dup of #21171, in which threads would get stuck waiting for that throttle and eventually be killed by the heartbeat checks. The preceding log lines should confirm that.
The fix was just merged into master and is about to go into the luminous branch for 12.2.1.
If your log doesn't include something about a heartbeat check failing on the blocked thread, please let me know!

Updated by Bob Bobington over 6 years ago
There are no log entries regarding failed heartbeat checks on the failing OSDs, only on the other OSDs witnessing the failure. None were logged before the first failure.

Hmm, I found another log file and came across this:

This must be what you meant. I was looking at the wrong log (systemd journal rather than /var/log/ceph/ceph-osd.1.log).
