Bug #8978
ceph ping not working as expected
0%
Description
Reading the doc: http://ceph.com/docs/master/rados/troubleshooting/troubleshooting-mon/
I came across command: ceph ping
Trying the command does not give me anything but error messages:
ceph ping mon.0
Error connecting to cluster: ObjectNotFound
ceph ping mon.1
Error connecting to cluster: ObjectNotFound
Trying it without an option
ceph ping
"ping" requires a monitor name as argument: "ping mon.<id>"
Try the monitor name for the <id>
ceph ping mon.t11
Error connecting to cluster: ObjectNotFound
Maybe just the name
ceph ping t11
"ping" expects a monitor to ping; try "ping mon.<id>"
My cluster status shows
ceph -s

I'm experiencing the same (on newly installed ceph-cluster via Ubuntu server 14.04.1):

Can you give me an example of how you are running the ceph ping command and the output you are seeing. I just tested it again with Giant, and it does not work for me:
