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,
Mark

For the past several months I had been building a
sizable Ceph cluster
that
will be up to 10PB with between 20 and 40 OSD
servers this year.
A few weeks ago I was informed that SUSE is shutting down SES and will no
longer be selling it. We haven't licensed our proof of concept cluster
that is currently at 14 OSD nodes, but it looks like SUSE is not going to
be the answer here.
I'm seeking recommendations for consulting help on this project since
SUSE
has let me down.
I have Ceph installed and operating, however, I've been struggling with
getting the pool configured properly for CephFS and getting very poor
performance. The OSD servers have TLC NVMe for DB, and Optane NVMe for
WAL, so I should be seeing decent performance with the current cluster.
I'm not opposed to completely switching OS distributions. Ceph on SUSE
was
our first SUSE installation. Almost everything
else we run is on
CentOS,
but that may change thanks to IBM cannibalizing
CentOS.
Please reach out to me if you can recommend someone to sell us consulting
hours and/or a support contract.
