  • System Replication is causing issues for the data volume reclaim due to snapshots on the primary.
  • You implemented the parameter changes recommended from KBA 1999880 FAQ: SAP HANA System Replication - Point 19: 'How can RECLAIM DATAVOLUME be executed when system replication is active?'
  • The reclaim is running for so long it is failing when daily backup runs with the following error:
  • Could not execute 'alter system reclaim datavolume <host>120 defragment' in <hours: mins:sec>. 
  • SAP DBTech JDBC: [2]: general error: Shrink canceled, probably because of snapshot pages. 
  • 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?
