running dbench on local FS in parallel also results in similar failures.

If samba is broken in this configuration we'll need to change our test (and report upstream, if we aren't using it incorrectly). Do you know if we're doing something particularly unusual, or this is a regression on their part?

not sambe issue. It's wrong to run two instances of dbench on the same test directory.

None of these failed tests are running it in parallel:

- workunit:
    clients:
      client.1:
      - suites/dbench.sh

And the workunit creates a separate dir for each client anyway; it's not sharing a directory.

At least, that's what's supposed to happen with these configs, and the only thing I see about multiple processes is when dbench itself starts up 10 on the second time through. What makes you think we're doing it wrong?

We're still occasional samba test failures, but I haven't diagnosed them carefully enough to know if they're this failure or the other one. I'll start doing that again soon.
