Swap as an LVM volume not working ?

Hello guys, i'm trying to make a fs layout with swap as a LVM logical volume, my autoyast configuration is something like this <partitioning> ... <drive> <device>/dev/vol</device> true <partitions config:type="list"> <partition> swap <mount>swap</mount> <size>1gb</size> </partition> <partition> .... <!-- other volumes /,/usr, etc ...--> ... </drive> .... </partitioning> During the installation process YaST tries to mount /dev/vol/swap as an reiserfs partition and got error code "-3003" :( Am I doing something wrong , missing some configuration ? Removing this swap partition under the /dev/vol device makes it all work... Thanks in advance ! []'s -- "If you really want something in this life, you have to work for it. Now, quiet!
