I have tried to install ceph using ceph-deploy but sgdisk seems to have too many issues so I did a manual install. After mkfs.btrfs on the disks and journals and mounted them I then tried to start the osds which failed. The first error was: #/etc/init.d/ceph start osd.0 /etc/init.d/ceph: osd.0 not found (/etc/ceph/ceph.conf defines , /var/lib/ceph defines ) I then manually added the osds to the conf file with the following as an example: [osd.0] osd_host = node01 Now when I run the command : # /etc/init.d/ceph start osd.0 There is no error or output from the command and in fact when I do a ceph -s no osds are listed as being up. Doing as ps aux | grep -i ceph or ps aux | grep -i osd shows there are no osd running. I also have done htop to see if any process are running and none are shown. I had this working on SL6.5 with Firefly but Giant on Centos 7 has been nothing but a giant pain. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
