Disk Recovery Part III

[me at mattgillen.net (Matthew Gillen)]

I see.
Well, it seems you learned the hard way that resizing partitions isn't
something that LVM was designed to handle.  That also explains why you
had a much easier time with qt_parted.

LVM's purpose is to allow you to shuffle fixed-size devices (or
partitions) around underneath the filesystem layer.  An approach to your
problem that would lend itself to the use of LVM would have been to
create a bunch of medium-sized partitions, then add or delete those
partitions to your LVM as desired (admittedly I don't know how that
approach would interact with vmware virtual disks).

But the situation you're in, with only 4 partitions (presumably all
needed), means you're stuck using qt_parted.
