== How to BTRFS RAID1? ==

Could we have a section explaining a bit of BTRFS RAID1? and recommendations? I just cannot find anything about it for nixos [[User:Woile|Woile]] ([[User talk:Woile|talk]]) 10:45, 6 September 2026 (UTC)

:What are you hoping to have answered? The purpose of this page is to show interactions between NixOS and BTRFS, not a comprehensive document on utilizing BTRFS. If you want to know how to create RAID 1 in BTRFS, read the [https://btrfs.readthedocs.io/en/latest/Volume-management.html official documentation]. There is no additional configuration needed in your system nix configuration. `nixos-generate-config` should automatically detect your mounted btrfs raid 1 volume like any other btrfs volume. I'll add a note explaining this on the wiki. [[User:Pigs|Pigs]] ([[User talk:Pigs|talk]]) 01:55, 7 September 2026 (UTC)

::Again, I'm still figuring things out with RAID-1, and I'm looking for someone's verification. But if I understand this comment correctly: https://github.com/nix-community/disko/issues/99#issuecomment-1368275363 for BTRFS RAID1 the disks must exists before creating the raid1.

::So I was thinking we could include a brief explanation of raid1, plus a warning if you are using disko (order alphabetically and do raid-1 on the last one), because I haven't found anything else about this, which could be a footgun.
