Frequently Asked Questions

## Do I have to reformat my bcache drive to use the new bcachefs ?

To use the caching device (cdev) with the new bcachefs, you will need to reformat it.
In principle this should not be a problem, as they can be removed from a backing device (bdev/bcache).

If you wish to reuse the backing device (bdev/bcache), you can't this is nolonger an option.

If you wish to use bcachefs as a filesystem you will have to format the backing device (bdev/bcache) with
the new filesystem.

## Does bcachefs still have the bcache caching functionality of block devices ?

No.
