    the tempDB issue was powerful enough to knock out the cluster drives.

    A disk full error shouldn't take a disk offline. What does the cluster log say?

  • RE: Auto update stats not good enough

    Guru Nagabhushan (10/5/2009)


    I am hoping that SQL 2008 doesn't have these issues and has a better algorithm for managing stats.

  • RE: Best Autogrowth/AutoShrink Practise for TempDB

    What does the SQL error log say? It's a file called Errorlog, just search for it, should be easy enough to find.
