[linux-lvm] lvm2 and initrd

[guillaume]

I wonder if my initrd affects the system, because after running the 
initrd, the VFS is unable to detect any partition of my group volume. 
Although "vgscan" and "vgchange -a y" detect the group volume.

Here is what initrd is doing (and me) :
 >>
Found volume group "vglfs" using metadata type lvm2
6 logical volume(s) in volume group "vglfs" now active
sh: no job control in this shell
ls -l /dev/mapper/{control,vglfs-racine}

VFS: Cannot open root device "mapper/vglfs-racine" or unknown-block(0,0)
Please append a correct "root=" boot option

Anyone got an idea ?

Guillaume.
