Filesystems

This set of submodules is provide ways to configure different filesystems for NixOS.

You can find the options at provision.fs, these can help with configuring:

• disk + filesystems via Disko
• basic enablement options for filesystems such as btrfs, zfs, nfs, ntfs, bcachefs
• filesystem + disk tools such as hddtemp, smartctl/smartd, automount
• initrd / stage-1 boot
  • unlock LUKS/native encrypted disks over SSH
  • grub, systemd-boot, systemd initrd supported

Module Options Reference for provision.fs

Smartd

Small wrapper around smartd service (smart daemon from smartmontools).

provision.fs.smartd = {
  enable = true;
  # autodetect is enabled by default to auto add drives to for monitoring
  autodetect.enable = true;
  # extra settings to add to `services.smartd`
  settings = {
    devices = [
      { "/dev/sda"; }
      { "/dev/sdb"; options = "-d sat"; }
    ];
  };
};

hddtemp

Support HDD/SDD temperatur monitoring, includes defaults to add disks from disko to enabled disks.

provision.fs.hddtemp = {
  enable = true;
  # this is enabled by default, adds disks from `disko.disk.*.device`
  automapDisko = true;
  # add your own drives
  drives = [ "/dev/dissk/by-label/XXXXXXXXXXXXXX" ];
};

Misc

# enable gvfs, udisks2 and devmon
provision.fs.automount = true;

# add ntfs3g to system packages
provision.fs.ntfs = true;

# shorthand to add LUKS devices
provision.fs.luks = {
  enable = true;
  devices.enc-root = "/dev/sda";
  # can then be referred to as `/dev/mapper/enc-root` elsewhere in config
};

# enable bcachefs as supported filesystem
provision.fs.bcachefs.enable = true;
