Dear Members of the Group,

I bought a full tower case with 8 SATA mobo recently. So far I attached 3 HDD with 3 TB each and an SSD to have Ubuntu Server on (sdd). I installed zfs-fuse and created my first ZFS pool

sudo zpool create data raidz sda sdb sdc

and after

sudo zpool list

I get

NAME   SIZE  ALLOC   FREE    CAP  DEDUP  HEALTH  ALTROOT
data  8.12T   147K  8.12T     0%  1.00x  ONLINE  -
 
Where I am supposed to get 5.5TB instead of 8.12 (1 disk is dedicated here for parity)

I was previously successful at doing this quite a while ago, using the same command line then had the pool destroyed. Do I have to format the disks again? If so what do I have to do to have them properly formatted?

Your help will be appreciated!

zpool list shows raw capacity, zfs list shows usable space. Compare the output of the two. If zfs list is correct you've actually succeeded.
