We probably need to look into making them more reliable. If possible, it could be a potential topic for lsf/mm raid discussion as Coly suggested in previous mail. Is current test can run the test for different raid level, say, "./test --raidtype=raid1" could execute all the *r1* tests, does it make sense to do it if we don't support it now. Thanks, Guoqing
