FC2 with LVM installation problem

[Bernard Fay]

Hello,

I am trying to install Fedora Core 2 for x86_64 (AM64).  

I want to use LVM and I setup my drive in the following way:

hde1	swap	768M
hde2	/	 512M
hde3	LVM	/usr		1024M
		/usr/local	 512M
		/var		 512M
		/tmp		 256M
		/home		2048M
		/opt		1024M

When anaconda start to install Linux it eventually reply with a message
about disk space:

"You don't appear to have enough disk space to install the packages
you've selected.  You need more space on the following file systems:

Mount Point	Space Needed
/mnt		252 M

Where are my 1024 M assign to it?

Thanks,
