Ceph » devops

I tried to build 3 node cluster using ceph-deploy on centos , but forgot to disable iptables service on one of the nodes and so it was stuck on ceph-create-keys.

soon after i created monitors [using "mon create" command], I tried to destroy the monitor running on the node, on which iptables was disabled and seeing an inappropriate error.

[ubuntu@burnupi05 ceph-deploy]$ ./ceph-deploy mon destroy burnupi21

we may have to handle this scenario more gracefully.
