Fresh Install of 5.1 Fails with ZFS - 'cannot create rpool: no such pool or dataset'

I'm trying to install 5.1 on a new pair of nvme SSDs using ZFS RAID1. Both drives have the most recent available firmware from Samsung, and both drives have 100% unallocated space with 0 partitions.

CLI output of the install shows the successful creation of GPT entries, but then stops on

Code:
cannot create 'rpool' : no such pool or dataset

Is there a pre-format requirement for ZFS as the OS filesystem? The wiki didn't seem to suggest so.

I also tried installing in debug mode to see if that would give me any more information. It got just as far in the installation process, created partitions, and gave a similar error as the first time around:

Code:
cannot create 'rpool' : one or more devices is currently unavailable[/cpde]

Edit: Nevermind. Just found this. Man. That's really disappointing. Has anyone successfully done this manually somehow?

It a zfs issue not proxmox.
Everything I have read so far tells me you can install on single disk but not on mirror.
The only solution as far as I can tell is, if your hardware supports it, get a pair of data add drives. Boot in legacy mode, change it in the bios, and install on data ssd. Use the nvme for slog or cache for your data pools.

Sorry, "add drives" ?

I was considering getting a pair of conventional ssd drives, plug them into SATA ports, and get mirrored ZFS on boot that way (and then use the nvme pair for ZFS-mirrored VM/LXC storage.

Sorry that is what I meant. Dumb auto correct. My post should have said sata ssd drives.
But you got the gist.
