Bonjour,

I have a problme with LVM:

I created a physical volume on a disk (say /dev/sda) using the command line:

pvcreate /dev/sda

Then a volume group on the same disk:

vgcreate suppl /dev/sda

Then a logical volume:

lvcreate -n sauvegardes -L 90g suppl

Then a file system:

mkfs -t ext3 /dev/suppl/sauvegardes

created a /sauvegardes directory

added the line

/dev/mapper/suppl-sauvegarges /sauvegardes ext3 defaults 1 2

to the fstab

and rebooted.

So far so good!

df gives:

/dev/mapper/suppl-sauvegarges
                     103212320   2326032  95643408   3% /sauvegardes

And I can use my "sauvegardes" directory, everything is OK.

But where are my physical volume, volume group, logical volume?

pvdisplay, vgdisplay, lvdisplay  do not mention it at all and the
graphical lvm manager shows my disck sda as "non initialisé", sda not
mounted, without any mount point and without any file system....

Am I dreaming?

What's wrong?

Thank for any light.
