Following this official howto
lvs shows you all volumes in their volume group (in my case ‘ssd’)

If the id of the new ct or vm is not equal to the id of the volume’s previous attachment, rename them, i.e.
lvrename ssd/vm-101-disk-1 ssd/vm-117-disk-2
This will make vm-101-disk-1 available as vm-117-disk-2, you have to increase the count in the end of the name.
Then edit the config of the actual vm.
Take the line from /etc/pve/qemu-server/<vm id>.conf that describes the volume to the new <vm id>.conf
The tricky thing was to run qm rescan afterwards which fixed syntax and made the volume appear in the web gui where i could finally attache it to the new vm.
