SYNOPSIS

dump.f2fs [ −i inode number ] [ −n NAT range ] [ −s SIT range ] [ −a SSA range ] [ −b block address ] [ −d debugging-level ] device

DESCRIPTION

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.

OPTIONS

Specify an inode number to dump out.

−n NAT range

Specify a range presented by nids to dump NAT entries.

−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.
