Well, migration from ReiserFS to EXT3 is not really a question for
FreeBSD list. :) They are both native to Linux; ReiserFS is fully
implemented in Linux only.

You might consider using UFS2 instead of EXT3 -- but I'm not
sufficiently sure if write support in Linux is still marked as
"experimental" (it was some time ago).

True, with a couple of not very interesting exceptions (it's possible
to convert EXT2 to EXT3 in place, and pure little window$ has a
built-in convertor from FAT32 to NTFS) -- as far as official
conversions are concerned; for unofficial, see below.

(Let someone corrects me if I'm mistaken, but it's not possible to
convert UFS to UFS2 in place.)

I think it's the best for you to do so. How much free space you have
there? You can shrink ReiserFS partition either from Linux or, maybe
easier, using GParted (http://gparted.sourceforge.net). Please note
that GParted surrently cannot resize Reiser4 partitions.

Or, if you are extremely brave, you can try


(I wouldn't do it.)

Every utility dealing with partition resizing will tell you to backup
your data first if you really need them. Since you can't do that, I'd
suggest reading ReiserFS manual and careful deciding what tool to use
for shrinking. But this is a Linux part of your job.

However, if you end up with one or two UFS2 partitions, then further
work with them will be a different story and you'll certainly get much
more answers. :)
