Port of scan_ffs utility to FreeBSD

2003-02-27 Thread Michael Ranner 

Hello!

I have started to add UFS2 support to Robert Watsons scan_ffs(8)
port from OpenBSD. Now it can recover properly the disklabel for
partitions with UFS1 and UFS2 filesystems. Scan_ffs has some
advantages over find-sb from /usr/src/tools, and it could fit
nice in the FreeBSD base system to recover lost disklabels
(ex. disklabel -rw ad0s1 floppy).

The output of scan_ffs -sl /dev/ad0s1, the original label was

  a:   52428804.2BSD 2048 16384 32776   # (Cyl.0 - 32*)
  b:  2097152   524288  swap# (Cyl.   32*- 163*)
  c: 209648250unused0 0 # (Cyl.0 - 1304)
  d:  2097152  26214404.2BSD 2048 16384 28512   # (Cyl.  163*- 293*)
  e:  1048576  47185924.2BSD 2048 16384 8   # (Cyl.  293*- 358*)
  f:  7372800  57671684.2BSD 2048 16384 28512   # (Cyl.  358*- 817*)
  g:  7824857 131399684.2BSD 2048 16384 28512   # (Cyl.  817*- 1304*)

should look like:

X: 524288 0 4.2BSD 2048 16384 1
X: 2097152 2621440 4.2BSD 2048 16384 1
X: 1048576 4718592 4.2BSD 2048 16384 1
X: 7372800 5767168 4.2BSD 2048 16384 1
X: 7824857 13139968 4.2BSD 2048 16384 1

So you simple have to replace X with the slice and to run disklabel -R ad0s1
and after this you can mount the filesystems.

Makefile, source and modified man pages are attached to this mail. Give it a
try and let me know your opinion.

This could be very useful!

Well, unless the code is magically encoded in the following block,
I think you forgot to attach something...
