Can't add new drive - shows as "partitions" under Usage

Hi there. Was hoping someone can help with what I thought would be a fairly simple operation: I was planning on adding some additional storage to my single node PVE system, so bought a couple of SSDs and plugged them in. I was planning on adding both as a new mirrored ZFS pool.

However, when I go to "disks" in the GUI, one of the SSDs shows "partitions" under Usage. But when I check that same disk in fdisk, there are definitely no partitions on that SSD - it's brand new. The other one is fine, and shows "No" under Usage.

The problem with the one that shows "partitions" is that when I go to ZFS (under Disks in the GUI), it only shows one of the SSDs as being available. The one that shows "partitions" does not show up. In addition, I can't Initialize GPT on that drive.

Not really sure what to do to enable usage of this drive with Proxmox. Any suggestions would be most appreciated.
 
Managed to figure this out. Even though fdisk didn't show any partitions, lsblk seemed to indicate that there was in fact a partition for about half the space of the drive. As I wasn't able to delete it, I just decided to create a new empty GPT partition table using fdisk. That seemed to do the trick and I was then able to create the ZFS mirror.

It worked for me too, thanks!
