I am running Ceph 0.78, Gentoo Ebuild. After completing step # 13, my /etc/ceph/ceph.conf file reads like this: ------------- [global] fsid = 6dcb9db5-b974-4164-83a0-381ea740a351 mon initial members = cephmon mon host = 10.208.39.100 ------------- When I try to start the monitor, nothing useful happens: --------------- # sh -x /usr/lib/ceph/ceph_init.sh start ++ dirname /usr/lib/ceph/ceph_init.sh + '[' /usr/lib/ceph = .

On the bullet list, just in beginning of the "Monitor Bootstrap" section, you may read: "Monitor Name: Each monitor instance within a cluster has a unique name. In common practice, the Ceph Monitor name is the host name (we recommend one Ceph Monitor per host, and no commingling of Ceph OSD Daemons with Ceph Monitors). You may retrieve the short hostname with hostname -s." So the guide will assume you actually follow this rule of thumb and is prepared with this in mind. Other sections of the documentation will get into more detail on portions relevant to IDs and whatnot, but I don't think this guide was meant to tell you exactly everything about everything. Should you follow the guide to the letter, you should not have any problems. I don't really know how you got around to end up with 'mon.a' while following the guide, 'a' being the id of the mon. But let's assume that's what you really want, in which case 'mon initial members = a' is correct. 'mon initial members' expects a list of all the monitors that are to be part of the initial quorum (or at least a majority of them). During the guide, following the general rule of thumb of 'mon ID should be the hostname', you would end up with a monitor 'mon.cephmon' (assuming 'cephmon' as the host of your server, as per your config shown above) and 'mon initial members = cephmon'. Should you for any reason have a problem while running the monitor after following the guide to the letter, please take a look into the logs and let us know. -Joao > > > --- > Thanks, > Dyweni > > On 2014-04-17 14:52, Dyweni - Ceph-Devel wrote: >> Hi, >> >> After following the directions >> (http://ceph.com/docs/master/install/manual-deployment/#monitor-bootstrapping) >> >> to manually deploy and bootstrap the monitor, I find that the init >> scripts will not start the ceph-mon process. >> >> I am running Ceph 0.78, Gentoo Ebuild. >> >> After completing step # 13, my /etc/ceph/ceph.conf file reads like this: >> ------------- >> [global] >> fsid = 6dcb9db5-b974-4164-83a0-381ea740a351 >> mon initial members = cephmon >> mon host = 10.208.39.100 >> ------------- >> >> When I try to start the monitor, nothing useful happens: >> --------------- >> # sh -x /usr/lib/ceph/ceph_init.sh start >> ++ dirname /usr/lib/ceph/ceph_init.sh >> + '[' /usr/lib/ceph = .
