[pve-devel] [PATCH ha-manager 09/13] Add crm command 'stop'

Fabian Ebner f.ebner at proxmox.com
Thu Sep 26 13:38:55 CEST 2019


Not every command parameter is 'target' anymore, so
it was necessary to modify the parsing of $sd->{cmd}.

Just changing the state to request_stop is not enough,
we need to actually update the service configuration as well.
