If your current server has one pool with a single disk, you have 3 choices...

1. Add the new drive as a mirror to the existing drive, adding redundancy but no additional capacity (in the GUI in TrueNAS 12.0 CORE or at the CLI in FreeNAS 11.3)

2. Add it to the pool as a stripe (CAUTION: no redundancy with this option... if either disk is lost, all data on both disks is lost)

3. Add it as a second single-disk pool... means all of your existing items such as jails and shares can't really use it, but will add the new capacity for storage and new shares/mounts. (no redundancy in this option either, but one disk lost doesn't lose the contents of the other disk).

Read up on ZFS... perhaps start with this:

I have a similar setup - small household NAS with a 2TB HDD, and I want to add capacity to the server. Can I add another HDD to the same media pool, or is that just not happening?

If you aren't worried about data loss, then adding another disk to the pool will leave you with a stripe of 2 disks, which has no redundancy, but the capacity of the two disks added together.

WARNING: loss of either one of those disks would then result in the loss of all data from the pool (including anything on the not lost disk).
