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.
-
-i inode number
- Specify an inode number to dump out.
-
-n NAT range
- Specify a range presented by nids to dump NAT entries.
-
-M Block map
- Show all the allocated block addresses given inode
number.
-
-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.
