I created my ZFS volume using zpool. I opted for RAIDZ2, as I want double parity for the extra fault tolerence..tolerance.
and if I check the status, thatsthat's all good...:
Am I not doing something correctly, or is it simply the case that using what is essentially 'software RAID' with ZFS uses takes up alota lot of space (2 or so of my 8TB HDD's worth!)
