During testing (mimicking BGP / port flaps) on our cluster we are able
to trigger a "_committed_osd_maps shutdown OSD via async signal" on the
the affected OSD servers in that datacenter (OSDs in that DC become
intermittent isolated from their peers). Result is that all OSD
processes stop. Is this a bug or a feature? I.e. is there a "flap"
detection mechanism in Ceph OSD?
If it's a bug it might be related to
http://tracker.ceph.com/issues/20174. We get similiar error message on
"12.2.0". Version "12.2.1" does not log
"-1 Fail to open
'/proc/0/cmdline' error = (2) No such file or directory
-1 received signal: Interrupt from PID: 0 task name: <unknown> UID: 0
