Qdb doesn't run tests against XFS filesystem in CI, so running on XFS might be unreliable . Feel free to upvote https://github.com/questdb/questdb/issues/2337 .

Thank you again, good to know. This is a dev environment of ours, it is not a problem. I also found a link to the supported file systems: https://questdb.io/docs/operations/capacity-planning/#supported-filesystem

In fact, our ARM CI worker uses XFS, so we could include XFS to the list of supported FSes. @Marius Gheorghies please correct me if I'm wrong.
