Add 2TB nvme drive to pool

[d3m3zs]

I have pool 2TB from two 1 TB nvme drives, raid0 and formatted as ZFS. 

 

Just simple question: 

Is it possible to add one more 2TB nvme drive and recreate raid0 4TB (1+1+2) and format as ZFS? 

 

I understand that I lose all data from current pool (I will make backup), but main question - does software raid0 in unraid has no restriction aout size? Because if unraid build pool as raidz0 - all drives should be the same size.

 

I see that probably unraid first of all create usual mdadm and the format ZFS, am I right? 

  pool: nvme
 state: ONLINE
  scan: scrub repaired 0B in 00:03:40 with 0 errors on Sat Nov  4 03:03:41 2023
config:

	NAME              STATE     READ WRITE CKSUM
	nvme              ONLINE       0     0     0
	  /dev/nvme2n1p1  ONLINE       0     0     0
	  /dev/nvme1n1p1  ONLINE       0     0     0

errors: No known data errors

Yes, but it would only use 1TB from the largest device, btrfs could use the 4TB in raid0.
