Before the limited voters feature, the "raft_ignore_nodes" test was relying upon the fact that all nodes will become voters. With the limited voters feature, the test needs to be adjusted to ensure that we do not lose the majority of the cluster. This could happen when there are 7 nodes, but only 5 of them are voters - then if we kill 3 nodes randomly we might end up with only 2 voters left. Therefore we need to ensure that we only stop the appropriate number of voter nodes. So we need to determine which nodes became voters and which ones are non-voters, and select the nodes to be stopped based on that. That means with 7 nodes and 5 voters, we can stop up to 2 voter nodes, but at least one of the stopped nodes must be a non-voter.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
