Due to a missing functionality in PythonTest, `unshare` is never used to mount volumes. As a consequence: + volumes are created with sudo which is undesired + they are not cleared automatically Even having the missing support in place, the approach with mounting volumes with `unshare` would not work as http server, a pool of clusters, and scylla cluster manager are started outside of the new namespace. Thus cluster would have no access to volumes created with `unshare`. The new approach that works with and without dbuild and does not require sudo, uses the following three commands to mount a volume: truncate -s 100M /tmp/mydevice.img mkfs.ext4 /tmp/mydevice.img fuse2fs /tmp/mydevice.img test/ Additionally, a proper cleanup is performed, i.e. servers are stopped gracefully and and volumes are unmounted after the tests using them are completed.

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.
