Did you try mounting with the force switch? it works for me all the time. IMO it's an OS or HD issue and not a breakin like what you have in mind. Although my scenario is a little bit different, I have several servers with raid5, the one with ubuntu always experiences failed raid devices while CentOS does not, the two ubuntu servers are running heron and gutsy respectively.
