I have a Server in my living room that runs Arch Linux. I originally set up this server to provide a NAS. The NAS serves as a backup solution for the clients in my network, and also stores my media collection. When I initially set it up, I had just one (Desktop!) HDD: A Seagate Barracuda with 8TB of storage. For the filesystem, I chose Btrfs at the time because I heard some good things about it, and looking through the features it seemed to do what I wanted. But the longer I used it, the more problems creeped up. It doesn’t have native filesystem encryption, so I had to use LUKS. It supports Quotas, but doesn’t have a good way of displaying how much storage a specific subvolume/snapshot actually uses. It supports snapshots, but not too many of them. I also thought that subvolumes were very neat, so I created a lot of them to give each “application” a unique path that I tried to cram into the FHS-Philosophy. This caused more trouble than it solved though, because now I had a lot of different paths that I had to write down. I also made a bash script to mount all of these different subvolumes, and had to frequently look inside this script to keep all of the paths and subvolumes together. And with every Service I added, I needed to update this mounting script. This wasn’t really hard or complicated, but very annoying.
