    Zpool unable to properly create a raidz pool


    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

    Code:
    sudo zpool create data raidz sda sdb sdc
    and after

    Code:
    sudo zpool list
    I get

    Code:
    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!

    Hi.

    A Google search for "zpool list" size brought up Different sizes between zfs list and zpool list which says in part:
    zpool shows the total bytes of storage available in the pool.

    zfs shows the total bytes of storage available to the filesystem, after
    redundancy is taken into account.
    That seems about right for your situation. What does
    Code:
    sudo zfs list
    show compared to zpool?

    Best wishes ... cheers, drl
