  1. Hello Kris and Allan,
  2.  
  3. I have two questions about ZFS. Is it possible to create zpool mirror with only
  4. one device and then add second one later? Also, is it safe to use disks of two
  5. different sizes and from different manufacturers (one WD 2tb and one seagate
  6. 1,5tb)? I suppose that it would be logical to first use smaller disk while
  7. creating zpool so there won't be problems adding second one later?
  8.  
  9. Also, while reading on creating zpool I've read about ashift option and that it
  10. is recommended for performance reasons to use zpool create with "-o ashift=12"
  11. option but I'm not entirely sure why, would you like to explain it to me in more
  12. detail?
  13.  
  14. As always keep up the great show!
