I made an EC 4+2 cluster with `crush-failure-domain=host`.
Later after adding more machines, I changed it from `host` to `datacenter`:
ceph osd erasure-code-profile set my_ec_profile_datacenter k=4 m=2
crush-failure-domain=datacenter crush-device-class=hdd
ceph osd crush rule create-erasure rule_my_data_ec_datacenter
my_ec_profile_datacenter
ceph osd pool set my_data_ec crush_rule rule_my_data_ec_datacenter
This seems to have worked, and `ceph osd pool get my_data_ec crush_rule`
outputs:
crush_rule: rule_my_data_ec_datacenter
But `ceph osd pool ls detail` still shows
pool 3 'my_data_ec' erasure profile my_ec_profile ...
with `my_ec_profile` instead of `my_ec_profile_datacenter`.
Is this a problem?
Who wins, the profile or the crush-rule?
If it's not a problem, it is at least confusing; can I fix it somehow?
Thanks!
Niklas
