We have been running a Luminous.04 + Bluestor for about 3 months in production. All the daemons run as docker containers and were installed using ceph-ansible. 540 spinning drives with journal/wal/db on the same drive spread across 9 hosts. Using librados object interface directly with steady 100MB/s writes to it.
We have not observed any major issues. We have had occasional OSD daemon crashes due to an assert which is a known bug but the cluster recovered without any intervention each time. All the nodes have been rebooted 2-3 times due to CoreOS updates and no issues with that either.
If you have any specific questions related to the cluster, please post them on this thread.

Bluestore is also the good answer
It works well, have many advantages, and is simply the future of Ceph
Indeed, and normally I wouldn't even ask, but as I say there's been some comments/threads recently that make me doubt the obvious Luminous + Bluestore path. A few that stand out in my memory are:
* "Useless due to http://tracker.ceph.com/issues/22102 " [1]
* OSD crash with segfault Luminous 12.2.4 [2] [3] [4]
There are others but those two stuck out for me. I realise that people will generally only report problems rather than "I installed ceph and everything went fine!" stories to this list but it was enough to motivate me to ask if Luminous/Bluestore was considered a good choice for a fresh install or if I should wait a bit.
Thanks,
Simon.
