Documented steps Run mc admin rebalance start ALIAS (needs admin:Rebalance) to distribute objects across all pools by free space Note that object versions already expired per the bucket's lifecycle rules are ignored by the rebalance Note that objects whose only remaining version is a DeleteMarker are also ignored - they are considered fully deleted Rely on the MinIO scanner to later capture and remove those expired objects and trailing DeleteMarkers; the rebalance will not clean them Use mc admin rebalance status ALIAS to confirm redistribution to roughly equal free space
Known gotchas This is a documented behavior difference: rebalancing explicitly skips expired versions and trailing DeleteMarkers, deferring to the scanner Do not expect a rebalance to reclaim space from lifecycle-expired data; clean those via lifecycle rules and scanner Requires the admin:Rebalance policy action Doc: https://min.io/docs/minio/linux/reference/minio-mc-admin/mc-admin-rebalance.html
