Hi,

Today i oredered a dedicated server from hetzner that has 2 nvme disks, 500gb each in software raid1 and i'm strugling creating a lvm storage.
Here's an output of some commands:

Fromhere you would need to create a volume group:

vgcreate volumegroupname /dev/md2
If you are looking to use LVM storage for VPS, that is all you would need to do. In the storage section of Virtualizor, you would select LVM storage, and point it to /dev/volumegroupname
