All that etcd stuff is specific to ceph-docker, it supports storing config options in there. Most of these features are obselete with the mon config store nowadays.
To answer the original question: all you need to recover your Ceph cluster are the mon and osd disks, they have all the data you need to get Ceph up and running.

Are you stuffing anything ceph-related there? If so, please tell us what.As previously said, ceph has no etcd concept so unless you somehow pull stuff out of ceph and feed it into etcd, ceph will be completely careless if you lose etcd data.May the most significant bit of your life be positive.
