More Home IT Upgrades

This past weekend I continued to upgrade our NAS server. Last weekend, I upgraded my raid array with an additional 8TB of mirrored storage. This yielded two old 4TB WD Blue HDD. I noticed that my case has a total of 9 internal storage bays. One was used by my 500GB SSD Boot Drive, and 6 were populated by HDD drives making up the current raid array. This means I have 2 more storage bays left. However these remaining bays were meant for 5.25″ storage devices like Optical Disc Players. For me to place my old 4TB WD Blue HDD into these bays, I will need a 5.25″ to 3.5″ bay converter. I had one, and purchased the other one on Amazon. I ended up buying the ORICO Aluminum 5.25 inch to 2.5 or 3.5 Inch Internal Hard Disk Drive Mounting Kit.

I also did not have enough SATA slots and purchased the IOCrest SI-PEX40071 SATA III 8 Port Controller Card. This card along with the 4 builtin SATA slots on the motherboard gave me enough SATA connections for my 9 drives.

Once I installed the old 4TB drives, I proceeded to create another md raid level 1 device and created a matching physical volume which I used to extend the current logical volume group. When the setup is completed, I ended up with a 20TB+ fully mirrored NAS server. I love LVM in combination of mdadm.

I figured while everything is fresh on my mind, I minus well proceed with the dreaded 16.04 to 18.04 Linux Ubuntu upgrade.

The upgrade was surprisingly very smooth. However the new version of OpenVPN caused some troubles. The new OpenVPN no longer works with my old PureVPN configuration files, because the certificate files that came from PureVPN used an outdated and deprecated hash algorithm. After getting the new configuration files from PureVPN, everything worked like a charm.

I also have to reinstall the Unifi Controller along with Let’s Encrypt certbot utility.

Super happy with the outcome and the upgrades should last another 2 to 3 years.
