I currently have a 4TB mirrored pool on spinning rust that is only using 16% of its capacity and I would like to replace them with two 2TB SSDs. My FreeNAS Mini 2.2 has two other pools and thus I cannot attach the two new 2TB SSDs in order to create another pool to which I might be able to replicate the data from 4TB to 2TB. Given I can only find answers that tell me this is impossible without destroying the pool and starting from scratch, I am wondering if the following might work:
1) I have a separate machine running ZFS on Ubuntu in the same network.
2) Install the 2x2 SSDs in a new pool (Pool2) on Ubuntu.
2) 'ZFS send' a fresh snapshot of the existing 4TB pool (Pool1) to Pool2.
3) Disconnect Pool2 from Ubuntu.
4) Disconnect Pool1 from TrueNAS and import Pool2.
5) Point TrueNAS to Pool2 as the pool for Apps and VMs as is currently the case for Pool1.
Thanks in advance.
