Bug #8599

Updated by Loïc Dachary almost 10 years ago

h3. Workaround 

 Use the rule_id instead of the ruleset. The rule_id for a given ruleset can be found with:  
 <pre> 
 $ ceph osd crush rule dump 
 ... 
     { "rule_id": 4, 
       "rule_name": "fastrgw", 
       "ruleset": 50, 
       "type": 1, 
 ... 
 </pre> 

 h3. Description 

 ceph osd pool set data crush_ruleset 50* was using CrushWrapper::rule_exists, which     checks for a *rule* existing, whereas the value being      set is a *ruleset*.
