macos – OSX Cant mount existing drive to new mountpoint, only default /volumes

Have a pre-existing graid enclosure (named localdisk) that Im trying to mount on /localdisk mounting point.

I am attempting to mount manually via terminal because I want to choose the mountpoint, not the default under /volumes.

First things fist, I am making sure the drive is unmounted, which it is.

Next, I am grabbing the name from diskutil list, which is /dev/disk2. Then, I am running , as root :

diskutil mount -mountPoint /localdisk /dev/disk2

This returns: Volume on disk2 failed to mount, if it has a partitioning scheme, use "diskutil mountDisk"

Okay, fine. So then I am running diskutil mountDisk /dev/disk2. This mounts it at the default point, under /volumes, which is not acceptable. So I unmount again, and then try:

diskutil mountDisk -mountPoint /localdisk /dev/disk2. As expected, this gives the standard “usage” return for when you are using improper syntax.
