OES 2015 SP1 server upgraded to OES 2018 SP1. Running GroupWise 18. GroupWise Disaster Recovery is backing up the GroupWise server. It needs NFS access to the GroupWise server. All was fine while on 2015. Since upgrading to 2018, backups will fail if the GroupWise server gets rebooted. So far the only fix I have found is to go to yast > network services > nfs server. I select next and verify the settings, then finish and quit. Then DR is able to connect and complete the backup. I am assuming there is some service or something that is getting started when I go through the yast process, but I haven't been able to figure out what it might be. "nfs-server.service" is already enabled. Any suggestions?
