Can LOB data ever be fragmented?

Hi All,

Looking at the following output of sys.dm_db_index_physical_stats on one of my tables, i noticed 2 rows for indid = 1. 1 for IN_ROW_DATA, 1 for LOB_DATA. Now i understand (i think) that if the table has LOB data (which mine does as ntext), it will show a row for the pages that the LOB_DATA is stored on.

My clustered index for that table down not include the LOB column.

So, when i look at the output of sys.dm_db_index_physical_stats, would i ever see the row where alloctype=LOB_DATA to show any fragmentation? Right now its 0% and the IN_ROW_DATA is 10%.

Just trying to figure out the 'use' of that row showing LOB_DATA, especially for fragmentation analysis, or is it merely informational?
