I tried using this > configuration: The ceph udev rules are going to automatically mount disks that match the ceph "magic" guids, to dig through the full logic you need to inspect these files: /lib/udev/rules.d/60-ceph-partuuid-workaround.rules /lib/udev/rules.d/95-ceph-osd.rules The upstart scripts look to see what is mounted at /var/lib/ceph/osd/ and starts osd daemons as appropriate: /etc/init/ceph-osd-all-starter.conf In theory you should be able to remove the udev scripts and mount the osds in /var/lib/ceph/osd if your using upstart. You will want to make sure that upgrades to the ceph package don't replace the files, maybe that means making a null rule and using "-o Dpkg::Options::='--force-confold" in ceph-deploy/chef/puppet/whatever. You will also want to avoid putting the mounts in fstab because it could render your node unbootable if the device or filesystem fails. -- Kyle _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
