Hi,
I have problems with the ceph-deploy command failing for reasons which
don't seem obvious. For instance, I was trying to add a monitor:
$ ceph-deploy mon add newmonhost
[Skipping some output]
[newmonhost][DEBUG ] checking for done path:
/var/lib/ceph/mon/ceph-newmonhost/done
[newmonhost][DEBUG ] create a done file to avoid re-doing the mon deployment
[newmonhost][DEBUG ] create the init path if it does not exist
[newmonhost][INFO ] Running command: sudo initctl emit ceph-mon
cluster=ceph id=newmonhost
[newmonhost][INFO ] Running command: sudo ceph --cluster=ceph
--admin-daemon /var/run/ceph/ceph-mon.newmonhost.asok mon_status
[newmonhost][ERROR ] admin_socket: exception getting command
descriptions: [Errno 2] No such file or directory
[newmonhost][WARNIN] monitor: mon.newmonhost, might not be running yet
[newmonhost][INFO ] Running command: sudo ceph --cluster=ceph
--admin-daemon /var/run/ceph/ceph-mon.newmonhost.asok mon_status
[newmonhost][ERROR ] admin_socket: exception getting command
descriptions: [Errno 2] No such file or directory
[newmonhost][WARNIN] monitor newmonhost does not exist in monmap
I have the keyring path specified in ceph.conf (pasted below).
What is weird is it works fine if I first copy the keyring file to
/var/lib/ceph/mon/ceph-newmonhost/keyring. Can anyone help me understand
why this step is not automated? I have had similar issues adding OSD's
before.
Some info (on the admin node):
$ ceph-deploy --version

Thanks for any help!
