This test complains about non-existing namespaces:

This is most likely caused by the automatic snapshotting that is not aware of dissapeared test namespace. The namespace is already deleted when the system tries to snapshot it, and throws this.

Workaround is disabling automatic snapshotting @ start of testing

The namespace should still be present as this test is only killing the proxies to verify the DTL.
This seems like an issue with Alba?
@jake9050 Was the volume still present at the time that snapshotting would occur?
