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.
23
25 -i inode number
26 Specify an inode number to dump out.
27
28 -n NAT range
29 Specify a range presented by nids to dump NAT entries.
30
31 -s SIT range
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
40 Specify a block address to retrieve its metadata information.
41
42 -d debug-level
