I agree 100% with Art. I have run into this issue from time to time. Typically adding a chunk in the primary server directly will create the chunk on the secondary without issue but occasionally I will have to create the file for the chunk on the secondary server prior to running the ONSPACES command on the primary. With the target file for the chunk on the secondary I have never seen the ONSPACES command fail.
Check the online.log on the primary and on the RSS node.Run onstat -g cluster on the primary to check the state of log transfer and apply.Regards,
