Issue:

 

 

Replication for a context does not appear to be running.   
   
    When replication are supposed to run, replication performance for a context shows no data is being replicated over the network.   
    replication show performance rctx://1

Cause:

 

 

Other replications are running that are using up all the streams available for replications.   
   
    From the ddfs.info log.   

      WARNING: ddboost-<datadomain.com-34018>: ddboost_api ERROR: ddp_filecopy_start() failed, Err: 5539-nfs filecopy start failed with replication stream limit exceeded (nfs: Out of Streams)   
                                                             

 

 

Resolution:

 

 

Determine if any ddboost application(s) are using all the replication streams for its Managed File Replication.  Consider reducing the number of streams available for Managed File Replication to allow other replications to use streams for its replications.   
    Review the current replication setup on the Data Domain to ensure the number of replication jobs that run is feasible for the number of streams allowed on the Data Domain.   
     
                                                           

 

 

Notes:

 

 

The log view command will allow you to examine the ddfs.info file.   
    log view debug/ddfs.info   
   
    If the log entries do not exist in ddfs.info, they may have been in older logs that have been rotated and compressed.  Create a support bundle and uncompress the older logs to search for the warning messages or open a service request with DELL EMC and upload the bundle for further analysis.
