[Fedora-xen] FC5/Xen LVM resize question

stupid question: did you resize the filesystem after extending the 
logical volume ?

http://www.die.net/doc/linux/HOWTO/LVM-HOWTO-9.html#ss9.9

this works for me:
- shutdown DomU
- extend LV in Dom0
- extend filesystem in Dom0
- restart (create) domU

in theory, with a filesystem that allows online-resizing (see link 
above), it shouldn't be necessary to shutdown DomU. But haven't tried yet.

extending the logical volume in Dom0 is surely a more elegant approach.
