Did I expand my storage correctly?

Did I expand my "low space" pool, correctly with 2xWD80EFAX 8TB disks using the Add vdevs option? https://youtu.be/V3zapubaNzY?t=315

I.e. not via extending or expanding...

Background: I'm following on from https://www.truenas.com/community/threads/upgrading-storage.79357/#post-550960

https://www.google.com/search?q=truenas+upgrade+pool gives me very poor search results. "https://archive.freenas.org/9.3/" is "Upgrading TrueNAS®"... pardon?

The TrueNAS documentation doesn't appear to mention **Expand pool**. This Reddit comment implies it might be a bad idea?! https://www.reddit.com/r/freenas/comments/ji7qas/upgrade_pool_option/ga57ig8/


Last additional question, is this https://s.natalian.org/2021-01-25/upgrade.png a wise action?

Can you post the output of "zpool status" (with code tags)?

Not if you think you might have to downgrade your version of FreeNAS/TrueNAS

Looks fine

This is actually a common point of confusion with the documentation. There are 2 ways to expand a pool:

1. Adding vdevs matching your current pool layout. This sets up a stripe between the current pool members and the new vdevs, which is what you’ve accomplished by adding a 2-disk mirror vdev to your existing 2-disk mirror vdev.
2. Replacing all pool members with larger disks, assuming you have a pool topology that allows disk replacements without data loss. After the last disk goes in and the resilvering completes, then vdevs in the pool will then reflect the larger disks.

Do you see an increase in your storage capacity in the GUI?
