I'm following the tutorial at http://docs.ceph.com/docs/v0.79/start/quick-ceph-deploy/ to deploy a monitor using
% ceph-deploy mon create-initial
But I got the following errors:
...
[ceph-node1][INFO ] Running command: ceph --cluster=ceph --admin-daemon /var/run/ceph/ceph-mon.ceph-node1.asok mon_status
[ceph-node1][ERROR ] admin_socket: exception getting command descriptions: [Errno 2] No such file or directory
...
I checked on the monitor ceph-node1, it turned out that there were asok file, but with it's `hostname` rather than the /etc/hosts alias e.g. ceph-node1:
[root@GZH-ZB-SA2-Kiev-116 ~]# ls /var/run/ceph/
ceph-mon.GZH-ZB-SA2-Kiev-116.asok mon.GZH-ZB-SA2-Kiev-116.pid
When creating the socket file, is it better to use some hostname-neutral or passing-from-admin-node name?
I think we shall at least modify ceph-deploy to run ceph --admin-daemon with the monitor's real hostname. Most users tend to use IP addresses or aliases rather than admin node's hostname.
