I'm baaaaack!!
After WEEKS of testing old hard drives, I finally have my unRAID server running under a temporary license.
Setting up the array was SUPER EASY. The hard part was reading the recommendations on hardware, which unRAID options and add-ons I wanted and the REALLY LONG process of preclearing the disks.
After playing musical
chairs drives with my existing computers, I now have 9 storage devices (not counting the boot flash drive), which keeps me under the 12 drive limit for the 2nd tier license. I still have some expansion room, too.
Last night I requested a 30-day trial license, started up my array, and it was off to the races.
I configured:
a) 2 x 2TB drives for parity (better than 1 -- for redundancy);
b) 4 x 2TB drives for data storage;
c) 2 x 500GB SATA SSDs for caching;
d) 1 x 500GB NVMe SSD "Unassigned", for Virtual machine storage, Plex metadata and caching, etc.
As a 2-drive SSD cache "pool", it provides 500GB of cache and a mirrored SSD for redundancy, so I don't lose anything stored there before it's written to the array. There is a job scheduled nightly to move cached data to the array. This is one way to compensate for the lower performance of the unRAID array design vs. a striped disk array.
It took 5+ hours for the cache and data drives to be formatted and for the 2 parity drives to synchronize. Everything reports "healthy", so that's nice to see.
Now I need to configure a new login, change the default passwords, add my Media shares, and so on.
Once I have everything setup properly, and the trial expires in 30 days (plus 2 additional 15 day extensions if they'll let me), I'll have to pay for the license. I like being able to test something for 2-3 months before committing financially.
My array provides 4 disks-worth of storage, so that's 8TB plus 4TB of parity "backup". I could opt for 2TB parity and 10TB of data, but I prefer more redundancy should the parity drive die. If the only parity drive dies, it can be rebuilt, but if another (data) drive dies, the array is lost. I can recover most of the data from the individual drives, but the array can't be mounted.
My least-used drive only has 2 months of activity on it, and the oldest has over 7 years. I'm using the next-to-newest and next-to-oldest drives for parity. They happen to be the same model and have 5900RPM speeds -- better than the 5400RPM the rest have.
If you decide to use unRAID, and you plan to use spare drives of various sizes, I recommend not getting a license -- even a trial one -- until you've 100% tested and decided on the drives to use. That can all be done without starting the array. I tested 17 drives just to see if they were all still good. 3 had to be "retired". 3 smaller ones replaced 2 x 1TB surveillance recording drives, which I then used to replace 2 x 2TB drives in my main PC. I couldn't justify having many TBs in the 2 workstations while running 8 smaller drives in the storage array. I hope to use the RAIDs more now for direct storage rather than my local drive, both for protection and network accessibility.
If, however, you plan to use all new drives, then the process of deciding on which drives to use and preclearing them is more streamlined and should only take a few days at most, depending on the size of the drives purchased.
Stay tuned. After I get the "housekeeping" taken care of, it'll be time to finally install Plex...the #1 reason for this project.
