wipedisk

I tried to format 3 drives (4TB, 4TB, 8TB) into a ZFS Array. This did not work. I then tried to format 3 drives into the other array types. This did not work. I proceed to format only 1 drive into a raid0 default drive. This did work. Now I want to wipe this empty drive. I then try wiping it...

Initialising with GTP: The command needed seems to be pvesh create /nodes/{node}/disks/initgpt (pve-docs) ...but I don't know hot to implement it. What would be the command to initialise /dev/sdc? Same problem with pvesh set /nodes/{node}/disks/wipedisk ...
