pool.attach
===========

Attach a disk to an existing vdev in a pool, converting a striped vdev to a mirror or extending an existing mirror to an n-way mirror.

This operation will format the new disk, attach it to the target vdev, and wait for resilvering to complete if the target is a RAIDZ vdev undergoing expansion.

Locking behavior: - If another attach operation is already using the same disk, this call will fail immediately with EBUSY rather than queueing. - If another attach operation is running on the same pool (but with a different disk), this call will queue and wait for the previous operation to complete. - Operations on different pools with different disks can run concurrently.

This method is a job.
