Physical volume pv1 not found

[gau]

Binary package hint: grub2

Using grub2 1.97~beta4-1ubuntu4.1 on Ubuntu 9.10:

Grub2 console shows "error: Physical volume pv1 not found" when I try to do "ls (grupA-home)/". Instead, if I try to do "ls (grupA-arrel)/", all files and directories on this volume are listed . Both volumes are formated on ext4
