Note that because data is checksummed, it will find data corruption, but as a result it takes longer to run since it needs to check all your data blocks too. Use the BTRFS storage driver Estimated reading time: 11 minutes To add a block device to a Btrfs volume, Copy-on-write is used to maximize storage efficiency and minimize layer size, and writes in the container's writable layer are managed at the block level. This should lead to decrease in the total numbers in the btrfs filesystem df output.
