This is the UFS2 version of ffsrecov, heavily (and I do mean _heavily_) based
|
|
on John-Mark Gurney's program of the same name. It does basically the same
|
|
thing, only it's a little more resistant to crashes caused by bad pointers,
|
|
offsets and the like, and it does a little more than his did. Don't contact
|
|
him for problems with this program, it's definitely _my_ fault if it breaks.
|
|
|
|
This program is not ready for prime time. It has some shortfalls, it has a
|
|
bunch of new options that are mostly undocumented and the manpage could
|
|
stand to be rewritten. One _good_ thing is that it now uses the libufs
|
|
library and is therefore not as dependent on carrying around low-level code.
|
|
|
|
On the other hand, it worked for me. Using this tool, I was able to recover
|
|
almost all of a several-hundred-gigabyte file system that had been stomped
|
|
by a misconfigured RAID controller. (That's why I wrote the thing in the
|
|
first place, in fact.) With the right knowledge and a lot of patience,
|
|
it is possible to recover most or all of a trashed file system, at least if
|
|
it's not _too_ trashed.
|
|
|
|
I'm releasing it under the Berkeley two-clause license in the hope that
|
|
someone with more time will pick it up, polish it and make something
|
|
a little more useful out of it.
