7       image
8

SYNOPSIS

10       dump.f2fs [ -i inode number ] [ -n NAT range ] [ -s SIT range  ]  [  -a
11       SSA range ] [ -b block address ] [ -d debugging-level ] device
12

DESCRIPTION

14       dump.f2fs  is  used to retrieve f2fs metadata (usually in a disk parti‐
15       tion).  device is the special file corresponding to  the  device  (e.g.
16       /dev/sdXX).
17
18       Currently,  it  can  retrieve  1) a file given its inode number, 2) NAT
19       entries into a file, 3) SIT entries into a file, 4) SSA entries into  a
20       file, 5) reverse information from the given block address.
21
22       The exit code returned by dump.f2fs is 0 on success and -1 on failure.

32              Specify  a  range  presented  by  segment  numbers  to  dump SIT
33              entries.
34
35       -a SSA range
36              Specify a  range  presented  by  segment  numbers  to  dump  SSA
37              entries.
38
39       -b block address
