Comment 1 Jason Dillaman 2019-06-13 15:29:10 UTC

Please enable debug logging, restart the 'rbd-mirror' daemon, and provide the resulting logs:

# ceph --cluster local set client.local debug_rbd 20
# ceph --cluster local set client.local debug_rbd_mirror 20

Comment 5 Jason Dillaman 2019-06-14 13:38:32 UTC

I don't require the mon logs.

Are there any additional logs from the rbd-mirror daemon client? I don't see any "librbd"-prefixed log messages in the provided log and the crash is in librbd. I would expect lots of log files in "/var/log/ceph/" with names like "local.client.local.<pid>.<cctid>.log". You can force all the logs to the same file by running the following and restarting the daemon:

# ceph --cluster local set client.local log_file /var/log/ceph/local.client.local.log

If you are getting the logs via some stdout/stderr scraping process instead of via log files within the container, you will need to enable librbd logging to stderr:

# ceph --cluster local set client.local log_to_stderr true
