This was because the bash script had `set -e` and cleanup is called before the test starts. Since the log wouldn't exist, it would fail. The fix was adding an `rm -rf`. See: https://github.com/gluster/glusterfs-patch-acceptance-tests/commit/fc1fdb39c37b2a19c1c6f201a49646c82facb919
Fix committed and deployed to all servers.
