Last night I blew away my previous ceph configuration (this environment is
pre-production) and have 0.87.1 installed. I've manually edited the
crushmap so it down looks like https://dpaste.de/OLEa
I currently have 144 OSDs on 8 nodes.
After increasing pg_num and pgp_num to a more suitable 1024
Oh duh… OK, then given a 4+4 erasure coding scheme, 14400/8 is 1800, so try
2048.

That did it.
'step set_choose_tries 200' fixed the problem right away.
Thanks Yann!

It wouldn't let me simply change the pg_num, giving
Error EEXIST: specified pg_num 2048 = current 8192
But that's not a big deal, I just deleted the pool and recreated with 'ceph osd

So it sounds like I should figure out at 'how many nodes' do I need to increase
pg_num to 4096, and again for 8192, and increase those incrementally when as I
add more hosts, correct?
