  • ZFS doesn’t really support mismatched disks. In OP’s case it would behave as if it was 4x 2TB disks, making 4 TB of raw storage unusable, with 1 disk of parity that would yield 6TB of usable storage. In the future the 2x 2TB disks could be swapped with 4 TB disks, and then ZFS would make use of all the storage, yielding 12 TB of usable storage.

    BTRFS handles mismatched disks just fine, however it’s RAID5 and RAID6 modes are still partially broken. RAID1 works fine, but results in half the storage being used for parity, so this would again yield a total of 6TB usable with the current disks.










    • 1TB NVMe SSD
      • 512 MB EFI
      • BTRFS partition for / filling up the rest
    • Ancient 128 GB SATA SSD
      • Swap
    • 1TB SATA SSD
      • 500 GB Windows installation for VR games
      • 500 GB BTRFS partition mounted at /mnt/games

    Since both my root and home are on the same BTRFS partition they share space.

    I have made sure to create sub volumes for the Steam and Game install directories, to avoid taking snapshots of them.

    Steam has 2 “libraries” registered, one in my home directory and one in /mnt/games






  • My home-assistant installation alone is too much for my Raspberry Pi 3. It depends entirely on how much data it’s processing and needing to keep in memory.

    Octoprint needs to respond in a timely manner, so you will want to have the system mostly idle (at least below 60 percent CPU at all times), preferably octoprint should be the only thing running on the system unless it’s rather powerful.

    If I were you, I would install octoprint exclusively on your Raspberry Pi 3, and then buy a Raspberry Pi 4 for the other services.

    I’m running Pi-hole and a wireguard VPN on an old Raspberry Pi 2, which is perfectly fine if you are not expecting gigabit speeds on the VPN.

    Yeah, there’s tonnes of good content on there, but as you allude to, there’s even more shitty or zero effort content… And the algorithm has a way of serving up absolute trash. And the parental controls are pretty much non existent…

    Youtube happily serves up videos to an 8 year old (on a supervised children’s account) that contain topics like abuse, sex, racism, horror, radical religious indoctrination, Chinese propaganda, and human centipede… This isn’t as rampant in the YouTube Kids app… But at least half the stuff on YouTube Kids is ASMR content or unboxing “surprise” toys…

    YouTube allows you to block channels, but will happily continue serving the 9000 other accounts that simply reupload the same exact videos.
