Hi, looks good. Because I've made an image fo the node's system disk I can revert to the state before the upgrade and restart the hole process. Thank you.

Because we don't want to upgrade ceph and the OS at the same time we deinstalled the ceph jewel components reactivated /etc/apt/sources.list.d/ceph.list with deb http://ceph.com/debian-hammer/ xenial main and pinned the ceph relaese to install in /etc/apt/preferences/ceph.pref Package: * Pin: version 0.94* Pin: origin ceph.com Pin-Priority: 999 Now after restarting the node the ceph daemons are not active and can't be started by /etc/init.d/ceph. It seems that this is caused by the missing systemd unit files for the mon and osd's in /lib/systemd/system/. What would be the right way to fix this? Maybe we could use the target and service files from https://github.com/ceph/ceph/tree/master/systemd but we don't know how to use it manually. And is there a way to upgrade Ubuntu with avoiding the ceph upgrade? Thanks in advance.
