Raidz2 with one drive redundancy

[aljanobin78]

Hello,
Hope this finds you well.

I'm building a new NAS with 6 x 6TB drives, and want to be in Raidz2.
the issue is one of these drives is currently in use, and 5 new ones.

Is there a way to build a raidz2 with a missing drive (so it has only one redundant drive) > empty the one in use right now in the NAS > rebuild the vdev with the current drive.
because my issue is I don't have a place to hold the data in this drive right now. and from my research, it seems ZFS doesn't support expanding a vdev (yet...).

I'm new to Freenas to be honest, I tried my best to look this up but it was hard to look up this subject with it being so similar to many others.

Thank you for your time.
