LV resize != fs resize.

Currently, you cannot online resize ext3, but that is only because the code
which I wrote to do this for 2.2 was never released, and it has not been
ported to 2.4/2.5 yet.

No, still only available as a patch. The ext2 online resizing patch is
very solid. The ext3 code is, by necessity, a total rewrite of the code
to work with ext3 journaling, but the fundamental concepts are the same.

Use ext2 + ext2online patch (not great, because you probably crash more
often than you need to resize), use ext3 but no online resizing (offline
resizing works just fine with ext2resize), or work on porting the ext3
resizing code to 2.4.
Cheers, Andreas
