  • The latest drive enclosures have been a bit of a fiasco.

The small one (6 drives) fits perfectly in one ATX Bay, however, the SAS SSD are too height to fit.

I fit 1 SATA3 SSD 1TB and 4 SATA3 HDD 2TB.

The other one, the 3 Bay 5.25″ SAS/SATA enclosure for 12 drives did not fit in the Corsair Obsidian Series 750D case, and I had to install it outside. Doing a DIY, as I explain in my book about assembling, fixing and upgrading your own PCs and laptops.

However the 12 Gbps SAS SSD were returning Checksum errors in ZFS when I did copy information or I ran scrub. I’m afraid the enclosure can only provide 6 Gbps at max, or a poor connection. Cables or expanders use to be the reason. I ordered new cables to make a direct connection to the HBA Controller without the enclosure to validate my theory and the drives stopped showing errors.

There is something good in all bad: I have been able to document and explain how to troubleshoot, actual errors in ZFS, in my book and talk about the problems with the cables, and the advantages of using a SAS controller even if you use SATA drives.

  • I got my first Excellent in an Assignment in an Ireland university, which makes me specially happy. And I keep going on studying in Linux Academy, the last course I did was GCP and Terraform, even if I knew both it helps me to keep my skills sharp.
  • I share with you some offers and charity bundles that I enrolled and enjoyed a lot:

There is an offer with Microsoft Pass which is that we can use Disney+ for free during 30 days.

  1. I started watching the Mandalorian, Season 2, and is wonderfully displayed in 4K.
    The quality of the video surprised me. Not that many contents in Netflix are 4K and I really enjoyed the great quality of the image.
  2. Humble Bundle offers a pack of 8 VR games per €13.45.
    If you like Virtual Reality and have your headset, this pack is amazing, and the benefits go to charity: Movember. The games are downloaded from Steam and the pack will last for 14 days.
  3. Humble Bundle offers a pack of Java and one go books for €12.65, with a minimum of €0.84 for 3 books. Benefits go for charity: Code for America.

Don’t forget to balance how much of your contribution goes to every player.

Unfortunately by default most of the money goes to O’Reilly and Humble Tip and few to the Charity cause. You can change that from the web when going to to the payment.
