The OpenZFS project has released version 2.1.13, of the open-source implementation of the ZFS file system and volume manager. ZFS supports features like data compression, data deduplication, copy-on-write clones, snapshots, and RAID-Z. It also supports the creation of virtual devices.

The new version is compatible with Linux kernels 3.10 to 6.5 and FreeBSD releases starting from 12.2-RELEASE. The release includes various changes and fixes, including improvements for Linux compatibility and bug fixes for issues related to automounted snapshots, L2ARC write size calculation, and memory leaks. The update also includes enhancements for zed, zfs-dkms rpm, and bash completion. Overall, the release brings improved stability and compatibility for users of OpenZFS/ZFS on Linux.

ZFS is a great choice for home servers and use on DIY network attached storage units, and is the file system that TrueNAS uses. It can also run perfectly well on the Raspberry Pi.

This article will show how to compile ZFS on Linux 0.8.2 on Ubuntu 18.04 on ARM64, specifically the FriendlyElec NanoPi M4 single board computer, which has a four-port SATA HAT available. It also works great on other single-board computers, and I’ve successfully compiled and used ZFS on the Raspberry Pi. These instructions will likely work on other architectures supported by ZFS on Linux, such as x86_64. Install ZFS build requirements Use apt to install the packages needed to build ZFS 0.
