LVM2: vgscan fails to recreate lvmtab

LINK

I recently moved an LVM array from one server to another. When I tried to recreate the lvmtab with pvscan/vgscan, it successfully found my 3 disks, but do not recreate lvm tab.

# pvscan -v

Found volume group "vg0" using metadata type lvm2


# lvscan -v

inactive '/dev/vg0/opt' [11.99 GiB] inherit

At the end, I have no /dev/vg0 and no /etc/lvmtab.

Any ideas?

lvchange -ay /dev/vg0/opt

The volume is not activeated, with this command you actually activate it.
