Cannot restore VM to newly created LV. Could Not Deactivate

[rsvg]

I had to expand my root LV, so I deleted my LV data, and then expanded root, that went fine. This was the process:

sudo rm -rf /var/lib/vz

sudo lvremove /dev/pve/data -y

sudo lvcreate -y --zero n -l 100%FREE -T -c 256K -n data pve

sudo mkfs.ext4 /dev/pve/data

But now when I try to restore a backup to this new lvmthin, I get this error.

this is my storage.cfg:

Hi,

sudo mkfs.ext4 /dev/pve/data

I'm suspecting this is the problem. A thin pool mustn't be formatted with a file system.

  Logical volume pve/data contains a filesystem in use.

I was able to solve this by comparing my storage.cfg to the default and removing a line. I think you’re right I did have to recreate the lm without a file system but now I can’t remember. Thanks for the help.
