[SOLVED] The current guest configuration does not support taking new snapshots.

[shore]

Hi!
I am new to PVE, and I am facing a problem that I don't know how to solve, I hope to get some help, thanks!

I have created a VM with the system ubuntu-server and I would like to create an initial snapshot before proceeding to the next step. But when I try to create it I encounter this error and the "Take snapshot" button is grey:

The current guest configuration does not support taking new snapshots

I've looked at similar issues and it seems to be related to the format of the drive, but I'm not sure how to change it.
Here is the hardware configuration of the virtual machine:

Thank you!

The question is - what type of storage is "data".
Can you please provide TEXT output encased in CODE tags of:
cat /etc/pve/storage.cfg
pvesm status
qm config 108

looks like the type of disk which called "data" is lvm.

LVM-type storage does not have snapshot-support ( see the storage-type table [1])
You'll either need to use the lvm-thin on the local disk, or convert the storage to ZSF, ZSF over iSCSI or Ceph(FS) if at all possible.

One "hacky" way to make a (storage) snapshot though: Migrate the data-disk to a different storage but keep the delete disk option off, and you'll have a disconnected clone of the drive on the old storage.

Thanks! I will try it!
