Problems importing existing datastore on zfs mirror back into new PBS install.

Been running Proxmox Backup Server as a VM in Proxmox VE.

In PBS VM I added two NVME drives, called sdb and sdc
When I created the datastore, I remember calling it PBS. (and thats about all I remember)

I created the 2 NVME drives into a ZFS mirror. 2x2TB

My question is, how to re-constitute the datastore from the ZFS mirror, and recover all my VM backups?

I had to reinstall Proxmox VE from scratch, and then recreated the PBS VM, and added the two NVME drives to the PBS VM.
The backups also include a backup of the PBS itself.

From what I can tell, the two mirror drives are still intact, as when trying to create a new Datastore, it says I have no unused disks, so presume it knows the disks are already in use.

Am a complete noob, so excuse my ignorance.
 
I seemed to have some luck by using zpool import with no other parameters.
It found a zpool called NVME, and I managed to import it.

zpool status reports the following:

zpool status
pool: NVME
state: ONLINE
scan: scrub repaired 0B in 00:01:07 with 0 errors on Sun Jun 9 00:25:08 2024
config:

NAME STATE READ WRITE CKSUM
NVME ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
sdc ONLINE 0 0 0
sdb ONLINE 0 0 0

errors: No known data errors

How do I recreate my datastore, now that the zpool seems to be there?
 
Even more luck.
Created a '/etc/proxmox-backup/datastore.cfg' and set it to '/mnt/datastore/NVME'

Refreshed the gui, and all my backups are accessable again.
