[linux-lvm] lv extend

[Tom Dawes-Gamble]

Hi,

Having looked at what e2fsadm(8) can do it's not really required
to make the changes I suggested.  I had a go at stupid things like
reduceing the lvol below the minimum size need for the file system
(which failed and left the lvol untouched. exactly like it should!)

I think I would favour adding [-A y/n] to e2fsadm and promote the use of 
e2fsadm for resizing ext2 file systems.  That said I don't really favour
the use of -A well not unless you are doing hundereds of operations on
the vg in one go.

Regards,
Tom.
