Hello Sid, You may try setting the 'noup' flag (instead of the 'noout' flag). This would prevent new OSDs from being set 'up' and therefore, the data rebalance shouldn't occur. Once you add all OSDs, then unset the 'noup' flag and ensure they're set 'up' automatically... if not, use 'ceph osd up <osdid>' to bring them up manually.
Hope this helps! Michael J.
