I have a bad node (it doesn't exist) in the mnesia cluster data when I get:
> mnesia:system_info(db_nodes)
[bad@node, ...]
How do I remove it from the cluster?
I tried:
> mnesia:del_table_copy(scheme, bad@node).
{aborted,{not_active,"All replicas on diskfull nodes are not active yet"...
What does this mean? How can I fix it?
Update. Before remove node from schema we need to stop mnesia on it
I had a similar problem years ago. What you are trying to do is remove an offline node, which as far as I am aware was impossible in earlier versions of mnesia.
You can however connect to the cluster using a dummy node named bad@node, and started with a tweaked system.config of the original clustered node. Once its online remove from the cluster.
