The test `test_mv_topology_change` is a regression test for scylladb/scylladb#19529. The problem was that CL=ANY writes issued when all replicas were down would be kept in memory until the timeout. In particular, MV updates are CL=ANY writes and have a 5 minute timeout. When doing topology operations for vnodes or when migrating tablet replicas, the cluster goes through stages where the replica sets for writes undergo changes, and the writes started with the old replica set need to be drained first. Because of the aforementioned MV updates, the removenode operation could be delayed by 5 minutes or more. Therefore, the `test_mv_topology_change` test uses a short timeout for the removenode operation, i.e. 30s. Apparently, this is too low for the debug mode and the test has been observed to time out even though the removenode operation is progressing fine. Increase the timeout to 60s. This is the lowest timeout for the removenode operation that we currently use among the in-repo tests, and is lower than 5 minutes so the test will still serve its purpose.

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.
