ZFS by design, to increase the RAID capacity, all disks (vdevs) in the array (zpool) wiil need to be equally in replaced with the same size disks in order for the zpool to inrease in size. Since unRAID looks to be only using JBOD, and I saw somewhere that it said that performance will only hit about 30-40 MB/sec without a cache pool, is this true? Also is the speed for the cache pool aggregate or is it per device?. I originally wanted to use ZFS RAID-Z2, which is a dual disk fault tolerant file system.

RAIDZ2 is not expandable at this point, but pool expansion does work, creating a stripe of all VDEVS in the pool with each new VDEV being key for pool survival, so adding a non-redundant VDEV will endanger the entire pool. It is recommended to have 1 GB of RAM per TB of storage. I have run literally hundreds of RAID arrays and the only one that has ever failed during a rebuild was one where the RAID card failed during the rebuild, this could have equally killed a ZFS pool also since it was writing garbage to the disks before it outright stopped functioning (assuming it was an HBA in this case).

If not, just select that show from the list. To copy the data in-place would require extra disks to create the initial ZFS pool, then copy data from the Unraid XFS disks to ZFS, as the XFS disks are freed up, add them as mirror vdev’s to the pool, and repeat. No enterprise configuration is needed for soft raid implementation (zfs hangs much on large quantities of ecc ram). I try to update the plugin as fast as I can, but sometimes it can be a couple of days.
