The reverse mapping btree maps filesystem blocks to the owner of the filesystem block. Most of the mappings will be to an inode number and an offset, though there will also be mappings to filesystem metadata. This secondary metadata can be used to validate the primary metadata or to pinpoi...

By default, if the DEVICE is a partition block device, mkfs.fat uses the partition offset relative to disk start. Otherwise, mkfs.fat assumes zero. Use this option to override this behaviour. -i VOLUME-ID Sets the volume ID of the newly created filesystem; VOLUME-ID is a 32-bit ...

Most of the mappings will be to an inode number and an offset, though there will also be mappings to filesystem metadata. This secondary metadata can be used to validate the primary metadata or to pinpoint exactly which data has been lost when a disk error occurs. By default, mkfs.xfs ...
