  • Could not execute 'alter system reclaim datavolume <host>120 defragment' in <hours: mins:sec>.

  • How can you stop the daily backup causing the volume reclaim to cancel? 
  • Is there any way to tell the progress of the data volume reclaim? i.e. how far through is it?
  • Is there any further advice for large data volume reclaims?
