Hi All,
    My undercloud has 48GB memories, and I am thinking to move memories to a compute node, so the final memories of the undercloud is 30GB, and I will do as per the following:
    1- Delete the discovered compute node
    2- Shutdown the undercloud as normal linux node.
    3- Swap the memories.
    4- Boot the undercloud
    5-  Rediscover the node.
    Is that correct? is 30GB for undercloud is enough?
 
Thanks,
 Ashraf
