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.
"error wiping '/dev/sdb': wipefs: error: /dev/sdb1: probing initialization failed: Device or resource busy"

I then try wiping it from the command line. This did not work.
"wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy"

What do I do?
Here are my guesses:
  1. Get a new 4TB drive as ZFS does not work well with 2 different drives of different sizes.
  2. Wipe that 4TB drive that was causing the problem from outside of Proxmox.
  3. Command Line Magic that I could not possibly guess.
Your help is appreciated.
Thanks,

is the pool you create imported? then you need to export/destroy it first.

in general, ZFS requires (approximately) identical sizes within a redundant vdev, so 4,4,8 effectively becomes 4,4,4 anyway (if you pass the flag to force creation, which is not offered on the UI for obvious reasons)
 
When I tried to create a ZFS array, I got this error.
command '/sbin/zpool create -o 'ashift=12' RG240217 raidz /dev/disk/by-id/ata-ST4000NE001-2MA101_WS251LZ9 /dev/disk/by-id/ata-ST8000VN004-3CP101_WWZ1BP5T /dev/disk/by-id/ata-ST4000NE001-2MA101_WS251534' failed: exit code 1

like I said - the UI doesn't support doing that, you need to create the zpool yourself on the CLI..
