While adding some nodes to a ceph emperor cluster using ceph-deploy, the new nodes somehow wound up with 0.80.1, which I think is a Firefly release. The ceph version on existing nodes: $ ceph --version ceph version 0.72.2 (a913ded2ff138aefb8cb84d347d72164099cfd60) The repository on the new nodes: $ cat /etc/apt/sources.list.d/ceph.list deb http://ceph.com/debian-emperor/ trusty main The ceph version on new nodes: $ ceph --version ceph version 0.80.1 (a38fe1169b6d2ac98b427334c12d7cf81f809b74) Inspecting the repository on ceph.com, it does look like it contains 0.72.2 packages. How did we get 0.80.1 instead? Is this expected behavior? Will it cause problems for us? Thanks for any advice!
