Oh my God... :-) Sorry for the tremendous lapsus.

Now it is working. Thanks.

jupiter:/etc/lvm# lvm dumpconfig
  No such command.  Try 'help'.

But don't worry. It appears I'm using an old version of lvm (I
downgraded to solve the "Internal error: unknown device-mapper task
16" problem).

jupiter:/etc/lvm# lvm version
  LVM version:     2.00.06 (2003-08-20)
  Library version: 1.00.05-ioctl-cvs (2003-09-01)
  Driver version:  4.1.0
jupiter:/etc/lvm#

I don't remember either... well, I'll trust you and I'll use lvm2 ;-)

Thanks for your help.
