Assume that a page is written to the journal but not yet updated to its actual location and before updating the actual copy the page gets invalidated. Now if a read comes to the same data, which block will be read: the journal copy or the actual copy ? First of all, will this situation ever occur ? The page will be marked dirty until it is written to its actual location so it may never get invalidated until it is written to the actual location! I appreciate your help. Since I'm not subscribed to this list, could you please CC your answers to my personal mailid. Thanks.
