Installing ZFS on Linux on Oracle Linux 7

We're going to add ZFS support to our Oracle Linux installation. We'll just add the ZFS on Linux Repo, verify the binary signature from GitHub, install the files, ensure the driver loads properly, and verify that it's functional. We'll save things like array creation for another document.

This is mostly a transcription of the process from the CentOS/RHEL ZoL installation manual.

Install the repo file

Add the ZFSonLinux repo and verify the fingerprint.

Note — manual fingerprint verification is atypical but we'll do it anyway just for kicks.

HOW TO: zstd

Why?

Way faster than bzip2, it's basically streaming compression with comparable compression levels.

Compress

tar -cvf - foo | zstd -f --no-progress -o foo.tar.zst
