Hi Chip,
Glad to hear it! From an upstream perspective we've got a pretty good
idea of some of the bottlenecks in the MDS and others in the
OSD/Bluestore, but it's always nice to hear what folks are struggling
with out in the field to challenge our assumptions.
Best of luck!

Mark,
We'll see if the problems follow me as I install Croit They gave a
very impressive impromptu presentation shortly after I sent this call
for help.
I'll make sure I post some details about our CephFS endeavor as things
progress, it will likely help others as they start their Ceph projects.

Hi Chip,
Regarding CephFS performance, it really depends on the io patterns
and
what you are trying to accomplish. Can you talk a little bit more
about
what you are seeing?
Thanks,
