Using "Nova Service-Force-Down"

  • Updated
Follow

Problem

While trying to run thenova command for service-force-down we get the following error.

# nova service-force-down <host uuid> nova-compute  
  error: unrecognised arguments: nova-compute

Looking at the usage of the command it tells us to use "ID" as the argument.

Usage: nova service-force-down [--unset] <id> does not specify which id to be used. 

Environment

  • Platform9 Managed OpenStack - v4.0 and Higher
  • Nova CLI (python-novaclient)

Procedure

  1. The ID to be used in the command is of the compute service for a host.    
    # nova service-force-down [--unset] <id>                                                                                               
  2. This ID can be obtained using the following command.  
    # nova service-list 
    The first column in the output of the above command will get you the id of the binary and this id should be used with the command nova service-force-down [--unset] <id> to force up or down the nova-compute service.
