I had a similar issue with Jewel on CentOS 7, but enabling ceph-mon.target fixed it for me. I deployed with ceph-deploy, which does enable ceph.target but not ceph-mon.target. Here's how it's supposed to work: $ systemctl list-dependencies ceph.target ceph.target ● └─ceph-mon.target ● └─[email protected] So ceph.target pulls in ceph-mon.target which pulls in the actual service. Now ams1-ceph01-mon01.service wants the ceph-create-keys@%i.service: $ systemctl list-dependencies [email protected] [email protected] ● ├─-.mount ● ├─[email protected] ● ├─system-ceph\x2dmon.slice Note, this is a Wants=, not a Requires=, so ceph-create-keys is allowed to fail, so it shouldn't block ceph-mon from starting. Then the question is indeed, why did it fail and did it even start? What does systemctl status for that service show for you? $ systemctl status [email protected] ● [email protected] - Ceph cluster key creator task Loaded: loaded (/usr/lib/systemd/system/[email protected]; static; vendor preset: disabled) Active: inactive (dead) Condition: start condition failed at Thu 2016-04-21 09:18:45 CEST; 3 weeks 2 days ago In my case this is a working cluster, so the keyring is already there and the service doesn't need to start (ConditionPathExists=!/var/lib/ceph/bootstrap-mds/ceph.keyring) Kind regards, Ruben Kerkhof _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
