   [root@ip110 ~]<demo># openstack help server resize 
   usage: openstack server resize [-h] [--flavor <flavor> | --confirm | --revert]
                                  [--wait]
                                  <server>
   
   Scale server to a new flavor. A resize operation is implemented by creating a
   new server and copying the contents of the original disk into a new one. It is
   also a two-step process for the user: the first is to perform the resize, the
   second is to either confirm (verify) success and release the old server, or to
   declare a revert to release the new server and restart the old one.
   
   positional arguments:
     <server>           Server (name or ID)
   
   optional arguments:
     -h, --help         show this help message and exit
     --flavor <flavor>  Resize server to specified flavor
     --confirm          Confirm server resize is complete
     --revert           Restore server state before resize
     --wait             Wait for resize to complete
