Yeah, The original source disk where all the data was from is a 16tb as well so moving things back to it wouldn't be an issue at all, just a time sink. So recommendation would be to copy all data from current zpool back to the 16tb in my pc, format the zfs disks, add to array (all but 1 for parity) copy back to the new array. Once finished, add parity drive and wait for sync? Now this would be an xfs array, not the cache pool, correct?
