dump.f2fs − retrieve directory and file entries from an F2FS-formated image
dump.f2fs [ −i inode number ] [ −I inode number ] [ −n NAT range ] [ −M Block map ] [ −s SIT range ] [ −a SSA range ] [ −b block address ] [ −d debugging-level ] device
dump.f2fs is used to retrieve f2fs metadata (usually in a disk partition). device is the special file corresponding to the device (e.g. /dev/sdXX).
Currently, it can retrieve 1) a file given its inode number, 2) NAT entries into a file, 3) SIT entries into a file, 4) SSA entries into a file, 5) reverse information from the given block address.
The exit code returned by dump.f2fs is 0 on success and -1 on failure.
−i inode number
Specify an inode number to dump out.
−I inode number
Specify an inode number and scan full disk to dump out, include history inode block
−n NAT range
Specify a range presented by nids to dump NAT entries.
−M Block map
Show all the allocated block addresses given inode number.
−s SIT range
Specify a range presented by segment numbers to dump SIT entries.
−a SSA range
Specify a range presented by segment numbers to dump SSA entries.
−b block address
Specify a block address to retrieve its metadata information.
−d debug-level
Specify the level of debugging options. The default number is 0, which shows basic debugging messages.
