I have twenty 2TB Samsung F4's that I want to set up as two 10 disk raidz2 vdev's under the same storage pool. I created the pool with the first 10 disks and then went to the expansion tab under pools, selected the next 10 drives, and set the redundancy as Raid6 (as with the original pool). The pools page reports 36.2T, but shouldn't this be more like 32T due to loss of space from redundancy? The filesystems page shows a total capacity of only 27.8T. Did I expand the pool incorrectly or is this a bug?
