Ceph » RADOS

Right now when you want to create a new crush rule via create-simple, you do something like:

ceph osd crush rule create-simple foo bar osd

which generates a rule with some ruleset value. When you want to assign the ruleset to a pool, you set it like:

ceph osd pool set baz crush_ruleset <value>

where value is whatever value the result is set to as shown in the crushmap. It would be far easier if you could use the rule name (or perhaps a ruleset name?) when assigning a pool a ruleset.
