Subject: [PATCH] rabbitmq-cluster: ensure we delete nodename if stop action
|
|
|
bef3ec |
fails
|
|
|
bef3ec |
|
|
|
bef3ec |
If the stop action fails, we want to remove the nodename from the crm
|
|
|
bef3ec |
attribute. Currently it is possible for the stop action to fail but
|
|
|
bef3ec |
the rabbitmq server does actually stop. This leaves the attribute
|
|
|
bef3ec |
still present. This means if the entire rabbitmq cluster is stopped,
|
|
|
bef3ec |
it is not possible to start the cluster again because the first node
|
|
|
bef3ec |
to start will think there is at least one other node running. Then
|
|
|
bef3ec |
the node tries to join an existing cluster instead of rebootstrapping
|
|
|
bef3ec |
the cluster from a single node.
