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.
This will install ZFS v0.7 release on OEL 7.7 and earlier, and ZFS 0.8 on OEL 7.8 and later.
