Description
There are known customer installations that don't use shared storage so failover mechanism might break such clusters.
There must be a knob in cmapi configuration file to disable failover facility if needed.
New
Changes has been made:
- add application section with auto_failover = False parameter to default cmapi_server.conf
- failover now is turned off by default even if there are no "application" section or no auto_failover parameter exist in cmapi_server.conf
- failover has now three different logical states:
- turned off - no failover thread started. To turn it on set auto_failover=True in application section of cmapi_server.conf file of each node and restart cmapi.
- turned on and inactive - there are failover thread but it doesn't work. It becomes active automatically if nodes count >= 3
- turned on and active - there are an active failover thread and it is activated. Can be deactivated automatically if nodes_count < 3
