scan_ffs
will take a raw disk device that covers the
whole disk or a file and will find all possible FFSv[12]/LFS partitions,
independent of block sizes on it. It will show the file system type (FFSv1,
FFSv2, or LFS), size, and offset. Also it has an option to show the values
with a disklabel-alike output.
The options are as follows:
-b
-e
end-F
file-l
-s
start-v
scan_ffs
is doing, and what
has been found.The device argument specifies which device
scan_ffs
should scan for file systems.
scan_lfs
is just another name for the same
program, both behave in exactly the same way.
scan_ffs
program first appeared in
OpenBSD 2.3 and then in NetBSD
3.1. Support for searching in files was added in
NetBSD 4.0.
scan_ffs
was written for OpenBSD
by Niklas Hallqvist and Tobias
Weingartner. It was ported to NetBSD by
Juan Romero Pardines, who added support for LFS/FFSv2,
partitions with fragsize/blocksize greater than 2048/16384 for FFSv1,
searching on files, etc.
scan_ffs
won't find partitions with
fragsize/blocksize greater than 8192/65536.
