Hi Kevan,
There's been a lot of big changes in the last couple of months so we're
slowly working on getting things back into a stable state. :) Thanks
for the report!

Greetings,
I have opened issue #16662 for a bluestore assert that happens when using
SSDs with I/O sizes larger than 4 MB. Below is the traceback. Inquiring
minds can look at the issue for an analysis of what is happening. If you
set 'bluestore_max_alloc_size' to 4194304 in ceph.conf, then you can avoid
this problem.
Cheers, Kevan
