I've actually managed to get a little further with my problem. As I've said before these servers are slightly distorted in config. 63 drives and only 48g if memory. Once I create about 15-20 osds it continues to format the disks but won't actually create the containers or start any service. Worse than that on reboot the disks disappear, not stop working but not detected by Linux, which makes me think I'm hitting some kernel limit. At this point I'm going to cut my loses and give up and use the small slightly more powerful 30x drive systems I have (with 256g memory), maybe transplanting the larger disks if I need more capacity.
