Previously the Ceph startup scripts required an enumeration of the daemons in the ceph.conf in order to start them. We've been doing a lot of incremental work since last October or so to make the system do more self-bootstrapping, and by the time we released Dumpling that got far enough to be used as the default configuration system (although it wasn't only for Dumpling). Now all the startup scripts will look in the default paths (or those specified by a ceph.conf in /etc/ceph, I believe) for anything that "looks like" a daemon, and start them up if they're present. This was the natural evolution of doing things like setting up udev rules that automatically ran any OSDs that have been created on a freshly plugged-in disk (which is how all the ceph-disk-[prepare|activate] stuff works). In general we find that this is easier to maintain since users are less likely to have conflicting ceph.confs across multiple nodes, and it doesn't present the illusion that a monolithic config file is necessary — but you are of course free to do otherwise if you prefer! -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com On Wed, Oct 9, 2013 at 12:30 PM, Wolfgang Hennerbichler <wogri@xxxxxxxxx> wrote: > I would also love to see this answered, this is sometimes asked during my geek on duty shift and I don't know a real answer to this, and I myself always do it old-(bobtail)-style. > > Wolfgang > -- > http://www.wogri.at > > On Oct 9, 2013, at 13:54 , su kucherova <su.kucherova@xxxxxxxxx> wrote: > >> Hi >> >> When I compare the /etc/ceph.conf for the latest release-dumpling and previous releases I find they are different. >> >> in the older release we had [osd],[mon],[msd] in the ceph.conf >> now i dont seem them.Where are these values stored now? >> How does ceph figure out the partitions of osd and journal >> >> Thanks >> Su >> _______________________________________________ >> ceph-users mailing list >> ceph-users@xxxxxxxxxxxxxx >> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
