Index Fragmentation

  • Hi all,

    I know this is a pretty common question, but I can't seems to find an answer anywhere....

    I am trying to defrag a number of indexes using the following criteria:

    Reorganise indexes with 5-30% fragmentation

    Rebuild indexes with > 30% fragmentation

    Indexes with over 1000 pages only

    The problem is, after the defrag has run there doesn't appear to be much change in any of the fragmentation levels - could anyone explain why this is? I know very small indexes will often not change, but these are all indexes with over 1000 pages, some with fragmentation levels of 98%+

    Any ideas why this can happen?

    Cheers

    Matt

  • can you post the output from sys.dm_db_index_physical_stats to give us more information to go on?

  • About how many pages are in the indexes you are noticing this on?

    Are the tables heaps?

  • Sorry I might have been a bit premature posting this - it appears my monitoring tool was not refreshing correctly. After a bit more in-depth investigation it looks like the indexes were indeed correctly defragmented....thanks for looking though!!
