Ok, so I'd already patched /usr/share/ganeti/2.15/ganeti/storage/bdev.py - what fixed it for me was mentioned in https://groups.google.com/forum/#!topic/ganeti/kApy2vclbmg but I'd missed it the first time around: [client] rbd_default_format = 2 rbd_default_features = 3 ... adding this to ceph.conf on the Ganeti node made things work. Just in case someone else runs into this issue again :)
