Hello, In which cases can the "mon_osd_full_ratio" and the "mon_osd_backfillfull_ratio" be exceeded ? More specifically, in case a subset of OSDs fail, if there isn't any more space left in the remaining OSDs to migrate the PGs of the failed OSDs without exceeding either the "mon_osd_full_ratio" or the "mon_osd_backfillfull_ratio of at least one OSD, how will the cluster behave ? Will it exceed the "mon_osd_full_ratio" or the "mon_osd_backfillfull_ratio" of one or more OSDs to ensure an "active+clean" state ? Best regards, Raphaël
