Hi all, Context : Lab Platform Ceph dumpling and firefly Ubuntu 12.04 LTS
I encountered a strange behavior managing the crushmap on a dumpling and a firefly ceph platform. I built a crushmap, adding 2 specific rules (fastrule and slowrule) in order to experiment tiering. I used "ceph osd get|setcrushmap" and crushtool to extract and ingest the updated crushmap in the system. I have to precise that I respectively associated 50 and 51 as ruleset numbers for the 2 new rules. The ingestion was good; I checked it by "ceph osd crush rule dump" I created 2 pools (fastpool and slowpool) As indicated in the doc, I tried to associate fastpool to ruleset 50 by "ceph osd pool set fastpool crush_ruleset 50" an error occurred : rule 50 doesn't exist As the rule_id of fastrule is 4, I did "ceph osd pool set fastpool crush_ruleset 4" and it works but it's not a correct behavior. If a ceph admin wants to manage the crushmap, he doesn't have to check the rule_id (that he cannot set) before updating the attribute crush_ruleset of pools. The way to manage the rules if the ruleset not the rule_id. I also tested that reingesting a crushmap (after for example changing the sequence of the rules in the decompiled file) causes a global update of the rule_ids. I can't imagine the impacts on a platform. Did someone encounter this behavior? Did I misunderstand how to configure a crushmap?
