Hi everyone, I try to understand how Ceph works with systemctl on Debian and it seems to be a mess. First question : why is /etc/init.d/ceph is used as a "ceph" service ? that's an old sysvinit script ! Second question: why this "ceph" service is handling everything while it should be the new "ceph.target" unit ? "ceph.target" is disabled ! Third question : why some components like OSDs are handled via systemctl whereas MONs are unable to be handled via systemctl ? Here examples : # systemctl status ceph-mon@* -l ● ceph-mon@\x2a.service - Ceph cluster monitor daemon Loaded: loaded (/lib/systemd/system/ceph-mon@.service; enabled) Active: failed (Result: exit-code) since Mon 2016-03-07 12:16:50 CET; 1min 55s ago Process: 1861 ExecStart=/usr/bin/ceph-mon -f --cluster ${CLUSTER} --id %i --setuser ceph --setgroup ceph (code=exited, status=1/FAILURE) Main PID: 1861 (code=exited, status=1/FAILURE) ● ceph-mon@5.service - Ceph cluster monitor daemon Loaded: loaded (/lib/systemd/system/ceph-mon@.service; enabled) Active: failed (Result: exit-code) since Tue 2016-03-01 12:46:27 CET; 5 days ago Main PID: 10600 (code=exited, status=1/FAILURE) ● ceph-mon@host2.service - Ceph cluster monitor daemon Loaded: loaded (/lib/systemd/system/ceph-mon@.service; enabled) Active: failed (Result: exit-code) since Mon 2016-03-07 12:07:48 CET; 10min ago Process: 31231 ExecStart=/usr/bin/ceph-mon -f --cluster ${CLUSTER} --id %i --setuser ceph --setgroup ceph (code=exited, status=1/FAILURE) Main PID: 31231 (code=exited, status=1/FAILURE) # systemctl status ceph-osd@* ● ceph-osd@15.service - Ceph object storage daemon Loaded: loaded (/lib/systemd/system/ceph-osd@.service; disabled) Active: active (running) since Fri 2016-02-26 19:04:45 CET; 1 weeks 2 days ago Main PID: 30211 (ceph-osd) CGroup: /system.slice/system-ceph\x2dosd.slice/ceph-osd@15.service └─30211 /usr/bin/ceph-osd -f --cluster ceph --id 15 --setuser ceph... ● ceph-osd@14.service - Ceph object storage daemon Loaded: loaded (/lib/systemd/system/ceph-osd@.service; disabled) Active: active (running) since Tue 2016-03-01 12:44:32 CET; 5 days ago Main PID: 9586 (ceph-osd) CGroup: /system.slice/system-ceph\x2dosd.slice/ceph-osd@14.service └─9586 /usr/bin/ceph-osd -f --cluster ceph --id 14 --setuser ceph ... ceph-osd ID's are automatically found, but ceph-mon ID's are not ! "systemctl start ceph.target" is not starting MONs on my systems ! What's in trouble ? How to handle this mess ? Thank you for your help Florent |
