[PVE-User] Problems with LVM over DRBD.

Hi,
We have a two nodes Proxmox cluster, using as storage LVM virtual disks
over DRBD.

Some days ago we reinstalled this cluster from scratch with the last
Proxomox version. For avoid service interruption we first reinstalled
one of the nodes and started all virtual machines in it and then
reinstalled the other node.

Up here all right.

We have the DRBD storage syncrhonized and updated in the second node but
when we put the DRBD storage in primary role in this second node, it is
not able to see nothing related with the LVM virtual disks. pvscan,
vgscan or lvmscan return nothing about the LVM virtual disks created
over the DRBD unit.

We have verified that the filters in the /etc/lvm/lvm.conf file are
correct. Indeed this file is identical in both cluster nodes.

We don't understand why the reinstaled second node is not able to see
the LVM virtual disks over the DRBD unit.
May someone help us with this problem?

Thank you very much in advance.
Best regards.
