Hello,
I have a ZFS Pool with a single vdev made out of 3x8TB drives in raidz1.
Now, I have an additional 4 drives that I'd like to add to that existing pool as a new vdev, also in raidz1.
After my first search, I found this post by a moderator about adding additional vdevs and how they have to be the same width (amount of disks):
However, this info is wrong: After reading up some more I found contradicting info, and upon trying it myself, it worked perfectly fine when doing it manually in the terminal. The pool mounts perfectly fine, too.
So I know ZFS can do this, and I tested around and also already managed to add the separate vdev to the pool using terminal:
The issue now is, that the Unraid Web UI only lets me select "1 group of 7 devices" when I try to mount the pool like this - and it ends up saying the pool isn't mountable.
Is there any way to work around this or is it planned to add this functionality (maybe in 6.13)? This pool I used for testing isn't my primary pool, but I'd love to add the 3x8TB HDDs to my main pool (which currently is made out of 5 disks) and it's kind of frustrating to be stopped by an Unraid limitation when the underlying file system clearly can do the job
