I've been trying to debug this problem that shows up when using
ceph-deploy, and have found some pretty weird behavior:
[ceph_deploy.gatherkeys][WARNIN] Unable to find
/etc/ceph/ceph.client.admin.keyring on ['issdm-2']
The below findings are on the monitor node after the failed gatherkeys.
The ceph-create-keys upstart script is run when ceph-mon starts, but
there is an error in syslog:
Jan 24 10:58:38 issdm-2 kernel: [71327.813051] init:
ceph-create-keys main process (26591) terminated with status 1
There is more info in /var/log/upstart/ceph-create-keys.log
INFO:ceph-create-keys:Key exists already: /etc/ceph/ceph.client.admin.keyring
INFO:ceph-create-keys:Key exists already:
/var/lib/ceph/bootstrap-osd/ceph.keyring
INFO:ceph-create-keys:Key exists already:
/var/lib/ceph/bootstrap-mds/ceph.keyring
INFO:ceph-create-keys:Talking to monitor...
Error initializing cluster client: Error
INFO:ceph-create-keys:Cannot get or create admin key, permission denied
However, there is still no ceph.client.admin.keyring in /etc/ceph.
Now I start and stop the monitor
sudo stop ceph-mon id=issdm-2
sudo start ceph-mon id=issdm-2
Now the following new output is in ceph-create-keys.log
no valid command found; 10 closest matches:
config show
help
log dump
get_command_descriptions
git_version
config set <var> <val> [<val>...]
version

config get <var>
0
admin_socket: invalid command

INFO:ceph-create-keys:Key exists already:
/var/lib/ceph/bootstrap-osd/ceph.keyring
INFO:ceph-create-keys:Key exists already:
/var/lib/ceph/bootstrap-mds/ceph.keyring
But the ceph.client.admin.key happens to now be in /etc/ceph/...
