def create_vdev(vdev, state, read, write, checksum)
  VirtualDevice.new(
    role: @role,
    name: vdev,
    type: vdev.start_with?('/') ? 'disk' : vdev.split('-').first,
    state: state.downcase.to_sym,
    read: read.to_i,
    write: write.to_i,
    checksum: checksum.to_i,
    virtual_devices: []
  )
end

#parse_line(line, stripped) ⇒ Object

Parse config line from zpool status

Lines start with a tab and then we decide based on indent level. Pool name has no indentation, vdev for redundancy is indented by two spaces and leaf vdevs by four spaces. If is replace going on or if there’s a spare, leaf vdevs are pushed to a lower level.
