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
-i " inode number" 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.
-d " debug-level" Specify the level of debugging options. The default number is 0, which shows basic debugging messages.
