[SOLVED] Problem in creating template and cloning with an LVM VG

[foadk]

Hi.
I followed the instructions from this page to create a vm:

wget https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img
qm create 9000 --memory 2048 --net0 virtio,bridge=vmbr0
qm importdisk 9000 bionic-server-cloudimg-amd64.img vms
qm set 9000 --scsihw virtio-scsi-pci --scsi0 vms:vm-9000-disk-0
qm set 9000 --ide2 vms:cloudinit
qm set 9000 --boot c --bootdisk scsi0
qm set 9000 --serial0 socket --vga serial0
qm template 9000
qm clone 9000 123 --name ubuntu2

vms is my LVM VG.
when I use an LVM-thin VG, everything works fine and I'm able to create a linked clone.
But with an LVM VG, when I run "qm template 9000" line, it doesn't convert the volume (vm-9000-disk-0) to a base volume (like it did with LVM-thin).
therefore when I run the clone command, it throws the error:

Linked clone feature is not supported for drive 'scsi0'

and it's only possible create a full clone.

Is there anything I'm missing here?

Regular LVM does not support thin clones - only full ones.
Check the reference documentation: https://pve.proxmox.com/pve-docs/chapter-pvesm.html
I hope this helps!

Thanks for your answer!
I'll use thin lvm.
