  • RE: SQL Server detected a logical consistency-based I/O error

    No good news then.

    The DB is damaged in such a way that CheckDB can't run, that makes the corruption irreparable. At this point I'd normally say 'restore from backup', but...

    When we get errors in this range, it usually mean the RAID controller or drives are failing. Yes, restore the data, after they verify the underlying storage.

    All corruption-related...

    I assume this is the one you tweeted about earlier.

    Yup.

    I strongly suspect it's not repairable. The page number the error gives is within the range I'd expect system tables...

  • RE: Long running query need to be tuned

    Additionally, logic-wise this is questionable - T1.TEMPLATE_FLG != 'Y' AND T1.TEMPLATE_FLG != 'P' OR T1.TEMPLATE_FLG IS NULL

    AND and OR without brackets. What's actually meant by this?

    I don't have clean backup. For some reason, my customer stopped weekly backup and the last backup is several month ago

    Since you don't have backup , try to...

    Too small for rebuilding to matter?

    It's unlikely that rebuilding the index fixed the problem. It's far more likely that the statistics update which the rebuild performs fixed your problem. Consider...

  • RE: SQL Server detected a logical consistency-based I/O error

    I hope that database isn't very important... It's very likely there will be some data loss here, it's possible that said data loss could be the entire DB.

    Weird question.

    gkramer 23701 (2/25/2014)


    So - if I measure CPU = 150 running an 8-core server (maxdop 0) the total CPU will be 1200

    No, 150.
