https://forums.freenas.org/index.php?threads/possible-to-add-5th-drive-to-4-drives-in-raid0.57385/#post-403724

In a nutshell, the vdev type mismatch warning in the GUI is being triggered when adding a single-drive vdev to a pool consisting of four single-drive vdevs. The pool is viewed by whatever generates the alert as having a single vdev of four drives, which is not the case.

Thats what it is. Each disk is considered a separate vdev in ZFS eyes.

We will not be encouraging people on shooting themselves in the foot. A pool configuration like that is crazy.
