[linux-lvm] lvcreate's man error (minor)

[Heinz J . Mauelshagen]

Estienne,

thanks for pointing the man page flaw out.
It is fixed in CVS at www.sistina.com now.


IRT your size related question: in case you use an older LVM version,
there was some bugs related to the > 1TB support for LVs.

If you upgrade to 1.0.3 those should be gone.

Regards,
Heinz    -- The LVM Guy --
