Evening all,
I originally posted under the FreeNAS subreddit but didn't quite get the full answer I was hoping for. Basically, does anyone have experience mixing VDEVs in a single pool in a home environment? I found a handful of older posts asking the same question but never a "this was the end result" summary.
Current setup is a Ryzen 3700x with 32 GB of RAM and a data pool made of one RAIDZ2 vdev of 8 x 4TB drives (78% full).
I have 6 x 10TB drives that I want to add to the existing pool as another RAIDZ2 vdev, however Freenas provides the warning of "Adding data vdevs with different numbers of disks is not recommended."
Limited google-fu suggests that adding another vdev of different composition *should* be safe as far as data integrity, but that performance *may* be impacted.
Thanks in advance.

- Does anyone have any firsthand experience with this?
- If I expand the pool but performance takes a significant impact, can I roll back to a previous snapshot from when there was only 1 vdev (acknowledging that I lose any data that was striped to the new vdev)?
Thanks in advance.
