Stops that which is started by stack.sh (mostly) mysql and rabbit are left running as OpenStack code refreshes do not require them to be restarted.

Stop all processes by setting UNSTACK_ALL or specifying -a on the command line

Keep track of the current DevStack directory.

Import common functions

Import database library

Load local configuration

Destination path for service data

Configure Projects

Plugin Phase 0: override_defaults - allow plugins to override defaults before other services are run

Import apache functions

Import TLS functions

Source project function libraries

Extras Source

Phase: source

Determine what system we are running on. This provides os_VENDOR, os_RELEASE, os_UPDATE, os_PACKAGE, os_CODENAME

Run extras

Phase: unstack

Call service stop

Swift runs daemons

Apache has the WSGI processes

Kill TLS proxies and cleanup certificates

BUG: tgt likes to exit 1 on service stop if everything isn't perfect, we should clean up cinder stop paths.

Get the iSCSI volumes

Stop MySQL server

Stop rabbitmq-server

Clean up the remainder of the screen processes

BUG: maybe it doesn't exist? We should isolate this further down. NOTE: Cinder automatically installs the lvm2 package, independently of the enabled backends. So if Cinder is enabled, we are sure lvm (lvremove, /etc/lvm/lvm.conf, etc.) is here.
