How to stripe across pools?

[meku]

I have two RaidZ2 pools and would like stripe them together to take advantage of the combined space.

Ideally I would like to avoid wiping both or even one of the pools because restoring from backup will be very slow. Is this possible to do using the GUI or CLI?

It is not possible.

If you have the space, you could always move all of the data to one of the pools, destroy the second pool, then add those drives as a second vdev into the first pool.

Thanks tvsjr, that was my intention but I couldn't find what the steps to achieve that were. After some experimentation I discovered that detaching one of the pools would cause the disks to show up in the Volume manager, which could then be assigned to the other pool.

Doing that will destroy the data on those disks
