Basically tells me "snapshots is something you can do" but nothing more.
Recently I tried doing a snapshot and got this as output:

When looking at my LVM, I see this:
And LVM thin says this:
It's not exactly clear to me why I'm seeing a warning about thin pools running out. Also, it's not clear to me on what storage this snapshot is taking space and if it's 96GB(the full disk size) or not.
What exactly would be some good steps here to learn about all this? And visualize it somewhere in the web GUI? I'm on version 7.4-3

Recently I tried doing a snapshot and got this as output:

I do see it in the output:On other clusters, I see the snapshot only taking, say, 4GB on a disk that's 64GB. And here I'm seeing 96GB of 96GB taken, the full 100%. Or am I mistaken?snap_vm-206-disk-1_testsnap pve Vri---tz-k 96.00g data vm-206-disk-1
