Do you mean that if I backup my pool, create a ZFS RAIDZ1 pool in unRAID and, in case I don't like unRAID, I can just continue with a newly created unRAID ZFS pool in the TrueNAS?
By the way, if I remove the swap partition on all of the drives and move the ZFS partition to sector 128 (or even without moving it), will unRAID be able to handle my pool?
And why does these swaps get created by default anyway?
