A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Goal:

  • 16TB mirrored on 2 drives (raid 1)
  • Hardware raid?
  • Immich, Jellyfin and Nextcloud. (All docker)
  • N100, 8+ GB RAM
  • 500gb boot drive ssd
  • 4 HDD bays, start with using 2

Questions:

  • Which os?
    • My though was to use hardware raid, and just set that up for the 2 hdds, then boot off an ssd with Debian (very familiar, and use it for current server which has 30+ docker containers. Basically I like and am good at docker so would like to stick to Debian+docker. But if hardware raid isn't the best option for HDDs now a days, I'll learn the better thing)
  • Which drives? Renewed or refurb are half the cost, so should I buy extra used ones, and just be ready to swap when the fail?
  • Which motherboard?
  • Which case?

How does the replacing of a HDD work on btrfs? Like if one failed and I'm using Debian, how do I rebuild the raid 1?

Or should I use an actual raid os?

Assuming that the disk is of identical (or greater) capacity to the one being replaced, you can run btrfs replace.
