October 5, 20232 yr What could be the cause in which drives formatted with XFS-encrypted show the full capacity while ZFS-encrypted shows a slightly reduced value? All three disks also show the exact same partition size
October 5, 20232 yr Community Expert zfs uses about 4% overhead for metaslab allocation and slop space reservation: https://wintelguy.com/2017/zfs-storage-overhead.html
October 5, 20232 yr Author I would have assumed the overall total disk size would have come from the disk level and not the filesystem level. XFS has similar metadata but unraid shows it as used space vs a reduction in capacity.
October 5, 20232 yr Community Expert zfs is different since it reserves that space, it can be changed if you want to be a little less.
