Bug #8324
closedpid files are not created
100%
Description
In Firefly (and I believe Emperor, too) PID files are not created in /var/run/ceph. This used to work in Dumpling.
ls /var/run/ceph
total 0
drwxr-xr-x 2 root root 100 May 9 19:46 .
drwxr-xr-x 22 root root 860 May 9 19:12 ..
srwxr-xr-x 1 root root 0 May 9 19:46 ceph-mon.node1.asok
srwxr-xr-x 1 root root 0 May 9 19:46 ceph-osd.0.asok
srwxr-xr-x 1 root root 0 May 9 19:46 ceph-osd.1.asok
ceph daemon mon.node1 config show | grep pid_file
"pid_file": "",
So it appears pid_file isn't properly being set. The docs [0] say it should default to /var/run/$cluster/$name.pid. Manually setting the pid_file location under [general], [mon], or [mon.node1] fail as well, even when metavariable substitution is not used. Affects OSDs, too.

The default for pid_file in firefly is indeed the empty string. However, if set in /etc/ceph/ceph.conf to
pid_file = /var/run/ceph/$type.$id.pid
it will be reported correctly with
# ceph-mon -i bm0402 --show-config | grep pid_file pid_file = /var/run/ceph/mon.bm0402.pid
but not with
# ceph daemon mon.bm0402 config show | grep pid_file "pid_file": "",
because it queries the local daemon instead of looking up the configuration file (this is normal, not a bug, as explained in the paragraph below).
When ceph-mon runs from upstart as /usr/bin/ceph-mon --cluster=ceph -i bm0402 -f the -f flag will not daemonize the process. The pid_file configuration string is reset to the empty string because CODE_ENVIRONMENT_DAEMON is not set. Since it is not daemonized, it will not even try to create the pidfile
However, if run manually, it will create the pidfile as expected:
# /usr/bin/ceph-mon --cluster=ceph -i bm0402 root@bm0402:~# ls -l /var/run/ceph total 4 srwxr-xr-x 1 root root 0 May 25 02:01 ceph-mon.bm0402.asok srwxr-xr-x 1 root root 0 May 23 17:41 ceph-osd.0.asok -rw-r--r-- 1 root root 5 May 25 02:01 mon.bm0402.pid
