Subject: [PATCH] rabbitmq-cluster: get cluster status from mnesia during
|
|
monitor
|
|
|
|
If mnesia is not running (for example if `rabbitmqctl stop_app` has
|
|
been called, or the service has paused during partition due to the
|
|
pause_minority strategy) then the cluster_status command to
|
|
rabbitmqctl will read the cached cluster status from disk and the
|
|
command returns 0 even though the service isn't really running at all.
|
|
|
|
Instead, force the cluster status to be read from mnesia. If mnesia
|
|
is not running due to the above or similar circumstances, the command
|
|
will catch that and properly fail the monitor action.
|
|
|
|
