NAME

6       dump.f2fs  -  retrieve directory and file entries from an F2FS-formated
7       image

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

26       -i inode number
27              Specify an inode number to dump out.
28
29       -I inode number
30              Specify an inode number and scan full disk to dump out,  include
31              history inode block
32
33       -n NAT range
34              Specify a range presented by nids to dump NAT entries.
35
36       -M Block map
37              Show all the allocated block addresses given inode number.
38
39       -s SIT range
40              Specify  a  range  presented  by segment numbers to dump SIT en‐
41              tries.
42
43       -a SSA range
44              Specify a range presented by segment numbers  to  dump  SSA  en‐
45              tries.
46
47       -b block address
48              Specify a block address to retrieve its metadata information.
49
50       -d debug-level
51              Specify  the  level of debugging options.  The default number is
52              0, which shows basic debugging messages.
