[https://zfsonlinux.org/ {{PAGENAME}}] ([[wikipedia:en:{{PAGENAME}}]]), also known as [https://openzfs.org/ OpenZFS] ([[wikipedia:en:OpenZFS]]), is a modern filesystem which is well supported on [[NixOS]].

Besides the ''zfs'' package (''ZFS Filesystem Linux Kernel module'') ~~<ref>https://search.nixos.org/packages?channel=unstable&show=zfs&query=zfs</ref>~~ itself, there are many packages in the ZFS ecosystem available.

Besides the {{nixos:package|zfs}} package (''ZFS Filesystem Linux Kernel module'') itself, there are many packages in the ZFS ecosystem available.

ZFS integrates into NixOS via the ~~<code>boot.zfs</code><ref>https~~:~~//search.nixos.org/options?channel=unstable&query=~~boot.zfs~~</ref>~~ and ~~<code>service.zfs</code><ref>https~~:~~//search.nixos.org/options?channel=unstable&query=~~services.zfs~~</ref>~~ options.

ZFS integrates into NixOS via the {{nixos:option|boot.zfs}} and {{nixos:option|services.zfs}} options.

In low-memory situations, ZFS therefore might need a bit longer to free up memory from its cache. The swap partition will help with that.

Example with gdisk:
