Description
When trying to create a pool with an incorrect PG number then the error message is hidden by a warning message.
osd_objectstore: filestore
# ceph --version
ceph version 12.2.12-48.el7cp (26388d73d88602005946d4381cc5796d42904858) luminous (stable)
# ceph osd pool create foo 2048
Error ERANGE: For better initial performance on pools expected to store a large number of objects, consider supplying the expected_num_objects parameter when creating the pool.
# echo $?
34
It's actually hiding the real pool creation error.
# ceph osd pool create foo 2048 replicated_rule 1 1000000
Error ERANGE: pg_num 2048 size 3 would mean 6504 total pgs, which exceeds max 6000 (mon_max_pg_per_osd 250 * num_in_osds 24)
# echo $?
34

That wasn't the initial issue reported.
What happen if you run "ceph osd pool create foo2 2048" instead ? (assuming you're using filestore).
