Hi Jaewook, Can you try following command: system host-update 3 personality=worker hostname=compute-0 The personality of compute node has changed from compute to woker.

However, it seems impossible to update new host. Please have a look at below result. [wrsroot@controller-0 ~(keystone_admin)]$ system host-update 3 personality=compute hostname=compute-0 compute-0: Reject attempt to configure with invalid personality=compute I think I installed 'all-in-one duplex extended'.. Is there any way to add new compute node? Thanks for any helps in advance.
