I have uploaded the old ext2-volume-v0.1.tar.gz to my web site,
http://www-mddsp.enel.ucalgary.ca/People/adilger/ext2-volume-v0.1.tar.gz

as I couldn't connect to tsx-11 lately, which is where I found it originally.
The good news is that the patch was developed for 2.1.42, so it is at least
half-way to working with 2.2.

I had another quick look at the README/code, and it looks like LVM will
help with some of the basic problems mentioned therein, such as handling
multiple disk names, changing e2fsck, changing the mount command.  All
of those problems go away because we are growing an LV, rather than
concatenating volumes.  The one trick will be to build the basic ext2
stuctures on the extended part of the LV without touching the current
filesystem - this may require modifications to mke2fs.  Another good thing
is that this definitely claims to work with a mounted filesystem, although
it requires a remount a-la "mount -o remount,rw...", but I think this will
work on an FS that has open files on it.

One note is that the original author, Miguel de Icaza, is no longer supporting
this code (he's busy working on GNOME), so don't bug him about it.

Cheers, Andreas
