For more information, seecurl -k -X POST 'https://<host>:8443/rest/volume/create?name=<vol_name>&path=<vol_mount_path>&tieringenable=true&tiername=<tier_name>&tieringrule=<rule_name>&offloadschedule=<schedule_ID>' --user mapr:maprvolume create. - An already tiering-enabled volume. For example:
For more information, seecurl -k -X POST 'https://<host>:8443/rest/volume/modify?name=<vol_name>&tiername=<tier_name>&tieringrule=<rule_name>&offloadschedule=<schedule_ID>' --user mapr:maprvolume modify.
