Hi,
Same use case... We do:
/usr/bin/ceph --admin-daemon /var/run/ceph/ceph-mon.*.asok mon_status | /usr/bin/json_reformat | /bin/grep state | /bin/grep -q leader && ...
Cheers, Dan

Hello fellow Ceph admins,
I have a need to run some periodic scripts against my Ceph cluster.
For example creating new snapshots or cleaning up old ones. I'd
preferably want to configure this periodic artifact on all my
monitors, but only execute it on the leader.
I've come up with the following oneliner:
ceph --admin-daemon /var/run/ceph/ceph-mon.*.asok mon_status | perl
-MJSON -0e 'exit((from_json(<>))->{state} != "leader")'
Has someone written up a quicker shortcut, preferably usable in bash?
Or did someone solve this entirely different?
Thanks in advance!
Regards,
Kai Storbeck
