  1. Hey there, So my best friend of 10 years and I decided to move in together 3 years ago. I'm a dev, and he was a sys admin. A couple years ago he started building a home server to run and manage things like Plex, Home Assistant, minecraft, etc, and I basically just watched in awe as he added to it over the years. Unfortunately, he passed away about 3 months ago, and that left me with inheriting everything in our home that I usually let him setup and maintain. I'm hoping you guys can maybe help me understand some things about the server so that I can keep it alive. Overall, I've been able to keep it going and troubleshooting things here and there, updating docker containers and rebooting once in a while when I see the processor kicking into overdrive without good reason. He's running Unraid 6.8.2 on it, and here are my questions: The Cache disk, under "SMART" is showing an error, but I see so many mixed explanations on the internet about what that means. Some people say it's the drive, it's the cable, it can be fixed via a scan, etc. To be honest, I don't even know what Parity means in this context, or why the "health" status is in a column called SMART. Does anyone have any insight on what I need to do to fix the cache disk error? I'd greatly appreciate it Here is what the hardware situation is. Can someone explain to me, what exactly is the device built into the table, underneath the server? I see cables corresponding to various things, but I'm unclear as to why. I'm guessing by the context clues that it's a giant switch, but I don't understand what it's switching exactly, and for what reason. I'm so afraid to touch it because I don't wanna accidentally tinker and change something without understanding how to fix it. There are two flashing lights, one orange blinking "Fault", and another green blinking "Fan". Would these be correlated? Do I need to replace the fan? I've been wondering how to back the server up? I'm more worried about something failing and losing all the configuration within Unraid, with all the docker containers and everything. Is there an easy way to backup the configuration/ setup of Unraid? These are my main questions for now, and I'd greatly appreciate any help in clarifying how this thing works. This thing is basically my biggest memory of him and our home together, and for the past few months I've been doing a speedrun on adulthood with him gone and no longer teaching me how to basically anything. He was the hardware guy, the builder guy, the bills guy, the random knowledge about any subject ever guy. It's incredibly important to me that I keep this alive. Thank you in advance. P.S. If anything, this experience taught me how important documentation is.
