The free space listed in "ceph df" and so on is based on "number of OSDs, times the free-size of the OSD with smallest amount of free space currently". Since you can't control where individual objects end up, "ceph df" will assume worst-case placement and hence give you info about the least possible space it can promise to give you, so if your objects dont get placed on the worst possible place, the "ceph df" output will not be lower by adding data until it makes a new OSD the smallest-free one. In the end, you need to wait until rebalancing has moved the data into the new OSDs so that one of the previous OSDs get more free space. This can take a while. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
