in the beginning, I create separate crush rules for SSD and HDD pool (
six Ceph nodes), following this HOWTO:
Now I want to migrate to the standard crush rules, which comes with
Luminous. What is the procedure here ?
# ceph osd crush rule create-replicated ssdpool default-ssd host ssd
# ceph osd pool set ssd-pool crush_rule ssdpool
# ceph osd crush rule create-replicated satapool default-hdd host hdd
# ceph osd pool set sata-pool crush_rule satapool
and wait, until everything is done ?
