I've recently had the job of system administration dumped in my lap. I'm looking forward to getting on top of it, but I'm a little behind the 8-ball right now. If my subject matter varies too far from the allowed context of this list, please don't flame me too badly. Background: We are running a dual PII 450 system with a 45 gig raid array, controlled by a DPT PM334. The O/S: FreeBSD 3.1-STABLE #1 For several months this has been rock solid. However, in the past three weeks, we've had a number of crashes, most of which seem to be related to mysql queries. The system would be totally unresponsive to ssh/telnet and web, but would still return pings. The server is colocated at our ISP, so it's been tricky to track down the exact 'on screen' console errors. Today, shortly after we upgraded our mysql version, I did see the error. (da0:dpt0:0:0:0): Invalidating Pack (da0:dpt0:0:0:0): Invalidating Pack devstat_end_transaction: HELP!! busy_count for da0 is < 0 (-1)! biodone: buffer already done (da0:dpt0:0:0:0): Read (10). CDB: 28 0 3 87 33 1f 0 0 80 0 (da0:dpt0:0:0:0): ILLEGAL REQUEST asc:20,0 (da0:dpt0:0:0:0): Invalid command operation code devstat_end_transaction: HELP!! busy_count for da0 is < 0 (-1)! biodone: buffer already done Followed by a complete system freeze, including the console. Some hunting and searching has led us to believe that we are encountering a driver failure and that we should bring the OS back to -stable. As I said, I haven't done this before, so I'm a little anxious. Before I take that step, I would be very greatful to hear some input from those who surely know more about this than I do. Is bringing the system back to -stable likely to correct our problem? Am I missing some indicator in the error above? Has someone else encountered similar trouble (and found a fix?) I'll be happy to take replies in private e-mail if this is off topic. Any help would be great.
