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.

This is the follow up to a post I wrote recently called From Require.js to Webpack - Party 1 (the why) which was published in my personal blog.

In that post I talked about 3 main reasons for moving from require.js to webpack:

  1. Common JS support
  2. NPM support
  3. a healthy loader/plugin ecosystem.

Here I'll instead talk about some of the technical challenges that we faced during the migration. Despite the clear benefits in developer experience (DX) the setup was fairly difficult and I'd like to cover some of the challanges we faced to make the transition a bit easier.
