LVM question

Hi Ed,
Thanks for your quick response.
Your note does makes sense.
The man page on e2fsadm however did suggest the resizing of a mounted or
unmounted ext2
file system. I think that is confusing if not incorrect.
e2fsadm tries to invoke ext2online and flags an error when it cannot find
it.
So something not quite right here.
Peter

Please read my note below again. In particular, the sentence that says the
file system must be unmounted first. RHEL 3 does not support resizing a
mounted file system.
