If that is the case and is "abandoned", I could start making it more to my liking to use it under FreeBSD. FreeBSD does not (yet) have this wild choice of init systems. Attempts to port Linux one to FreeBSD are in progress, but if they make it to a large crowd is questionable. Unless it is incorporated in the the FreeBSD release itself. > Yeah.

So systemd is digging around in /dev and /sys proding for devices with Ceph properties, and then starts the required ceph-(mon|osd|mds|mgr). Or Udev-events telling systemd to act on a device that presents itself in the system? So on an average system there is no OSD info in /etc/ceph/ceph.conf > -Greg > >> Cheers, >> Nathan >> >> >> On 04/20/2017 10:55 AM, Willem Jan Withagen wrote: >>> >>> On 19-4-2017 22:47, Gregory Farnum wrote: >>>> >>>> On Fri, Apr 14, 2017 at 1:44 PM, Willem Jan Withagen <wjw@xxxxxxxxxxx> >>>> wrote: >>>>> >>>>> Having solved the first few step in ceph-deploy, I can now get to the >>>>> point where it actually wants to start the first monitor. >>>>> Like: >>>>> /usr/local/bin/ceph-deploy mon create-initial >>>>> >>>>> And if I look at the other platform booting the inital monitor is >>>>> started thru the init|systemd|upstart.... >>>>> >>>>> However under FreeBSD bsdrc I require atleast in ceph.conf >>>>> [mon] >>>>> host = cephtest >>>>> >>>>> This is not the case on the other platforms? >>>>> >>>>> And how would I otherwise get this into the ceph.conf? >>>> >>>> >>>> I think you're running into some annoying deployment sharp edges here. >>>> The monitor "host" config value has gone in and out of being necessary >>>> at various times — the whole monitor boot sequence is pretty finicky >>>> so I've added Joao to the thread.
