LVM

lvm is a utility to create logical volumes.

Create VG for proxmox

We will use /dev/sdb as our drive.
Setup the disk for the physical volume with sgdisk -N 1 /dev/sdb.
Then create the physical volume pvcreate /dev/sdb.
The previous step can come to a halt when the device already contains an old
partition table and will display the error Device /dev/sdb excluded by a filter.
This can be solved by removing the old partition table with wipefs -a /dev/sdb.
And finally create the volume group vgcreate vmdata /dev/sdb.
Then follow the guide in proxmox on how to connect a vg to proxmox.
