|
This option specifies the driver to be used for the servicegroup service.
|
|
|
|
ServiceGroup API in nova enables checking status of a compute node. When a
|
|
compute worker running the nova-compute daemon starts, it calls the join API
|
|
to join the compute group. Services like nova scheduler can query the
|
|
ServiceGroup API to check if a node is alive. Internally, the ServiceGroup
|
|
client driver automatically updates the compute worker status. There are
|
|
multiple backend implementations for this service: Database ServiceGroup driver
|
|
and Memcache ServiceGroup driver.
|
|
|
|
Possible Values:
|
|
|
|
* db : Database ServiceGroup driver
|
|
* mc : Memcache ServiceGroup driver
|
|
|
|
Related Options:

* service_down_time (maximum time since last check-in for up service)
