November 6, 20232 yr 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
