All-in-one is using local storage, not shared storage. So you can't use the
local unshared data domain for a second host.
You may want to move the host to maintenace, detach it from
local_datacenter, attach it to default, create a nfs data domain and attach
it to default and then add a second host there.
Or you may explore Hosted Engine solution.
