Hmm. It doesn't work anymore with ext2resize 1.1.19-4. If I
downgrade to 1.1.19-3, it works again. You've broken it! Bad, bad
Petter! :-)

Using 1.1.19-4, the ext2online step yields:
ext2online v1.1.19 - 2001/03/18 for EXT2FS 0.5b
ext2online: unable to resize /dev/mapper/echo-test
There's only code for online resizing in ext3, not ext2 (in the
kernel.org tree, anyway). See /usr/share/linux/fs/ext3/resize.c.
Also the current resize2fs program from e2fsprogs Mercurial repository
is able to do online resizing (tested it and it works fine), so IMHO
the ext2resize suite is quickly losing its relevancy... I don't really
see why anyone would want to use these tools over the ones included in
e2fsprogs, as the latter obviously enjoy much better upstream
maintenance. Only ext2prepare-equivalent functionality is missing from
e2fsprogs now.
I'm using an unmodified linux-image-2.6.15-1-k7 (version 2.6.15-8), by
the way.
