[gentoo-user] LVM2 problem

[Hung Dang]

Hi all
I have a strange problem with LVM2. I follow this guide
http://www.gentoo.org/doc/en/lvm2.xml to create the LVM2 volume named vg
then create the logical volume /dev/vg/data. Everything went fine and I
can mount the volume /dev/vg/data to /mnt/data without any problem.
However, when I restart my computer the logical volume is disappeared.
I  can always replicate this problem by create a new LVM group then
restart my computer.

Any suggestion ?


Thanks
Hung
