Hello all, Over the past few weeks I've been trying to go through the Quick Ceph Deploy tutorial at: http://docs.ceph.com/docs/jewel/start/quick-ceph-deploy/ just trying to get a basic 2 OSD ceph cluster up and running. Everything seems to go well until I get to the: ceph-deploy osd activate ceph02:/dev/sdc ceph03:/dev/sdc part. It never actually seems to activate the OSD and eventually times out: [ceph02][DEBUG ] connection detected need for sudo [ceph02][DEBUG ] connected to host: ceph02 [ceph02][DEBUG ] detect platform information from remote host [ceph02][DEBUG ] detect machine type [ceph02][DEBUG ] find the location of an executable [ceph_deploy.osd][INFO ] Distro info: CentOS Linux 7.2.1511 Core [ceph_deploy.osd][DEBUG ] activating host ceph02 disk /dev/sdc [ceph_deploy.osd][DEBUG ] will use init type: systemd [ceph02][DEBUG ] find the location of an executable [ceph02][INFO ] Running command: sudo /usr/sbin/ceph-disk -v activate --mark-init systemd --mount /dev/sdc [ceph02][WARNIN] main_activate: path = /dev/sdc [ceph02][WARNIN] No data was received after 300 seconds, disconnecting...

[ceph03][DEBUG ] find the location of an executable [ceph03][INFO ] Running command: sudo /bin/ceph --cluster=ceph osd stat --format=json [ceph03][INFO ] Running command: sudo systemctl enable ceph.target Machines involved are ceph-deploy (deploy server), ceph01 (monitor), ceph02 and ceph03 (OSD servers). ceph log is here: http://pastebin.com/A2kP28c4 This is CentOS 5. iptables and selinux are both off. When I first started doing this the volume would be left mounted in the tmp location on the OSDs. But I have since upgraded my version of ceph and now nothing is left mounted on the OSD but it still times out. Please let me know if there is any other info I can provide which might help. Any help you can offer is greatly appreciated! I've been stuck on this for weeks. Thanks! -- Tracy Reed
