Testing phase 2 - three machine all-in-one deploy.
Deployed using eoan - mon,mgr and 1 x osd on each machine
Deployment seeded with pools a lightweight test data - rbd's in each
pool.
Each machine upgraded in turn (1,2 and then 0) using do-release-upgrade.
ceph versions checked throughout deployment - mixed versions observered.
OSD's booted OK after machine reboots post do-release-upgrade.
During upgrade process:
$ sudo ceph mon dump | grep min_mon_release
dumped monmap epoch 1
min_mon_release 14 (nautilus)
$ sudo ceph versions
