Still works:
quincy-1:~ # ceph osd crush rule create-simple simple-rule default osd
quincy-1:~ # ceph osd crush rule dump simple-rule
{
"rule_id": 4,
...
quincy-1:~ # ceph config set mon osd_pool_default_crush_rule 4
quincy-1:~ # ceph osd pool create test-pool6
pool 'test-pool6' created
quincy-1:~ # ceph osd pool ls detail | grep test-pool
pool 24 'test-pool6' replicated size 2 min_size 1 crush_rule 4
object_hash rjenkins pg_num 1 pgp_num 1 autoscale_mode on last_change

Hi,
for me this worked in a 17.2.7 cluster just fine
Huh, interesting!
(except for erasure-coded pools).
Okay, *that* bit is expected.
https://docs.ceph.com/en/quincy/rados/configuration/pool-pg-config-ref/#confval-osd_pool_default_crush_rule does say that the option sets the "default CRUSH rule to use when creating a replicated
pool".
quincy-1:~ # ceph osd crush rule create-replicated new-rule default osd hdd
Mine was a rule created with "create-simple"; would that make a difference?
Cheers,
Florian
