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.

 No Additional Properties

Target Vdev

Type: string

The GUID of the vdev where the disk needs to be attached. In the case of a STRIPED vdev, this is the STRIPED disk GUID which will be converted into a mirror. If target_vdev is already a mirror, it will be converted into an n-way mirror.

New Disk

Type: string

Name of the new disk to attach.

Allow Duplicate Serials

Type: boolean Default: false

Whether to allow attaching disks with duplicate serial numbers.

Result

Type: null
