To keep the copies mounted, run the following command in the mount host instantly after mount:SystemCtl daemon reloadThis is a manual process. Now AppSync code embedded this in AppSync 4.2 onwards to automate the run of the following by adjusting an AppSync setting on the mount host to true.SystemCtl Dameon reload run Upgrade to AppSync 4.2 if needed and follow the procedures noted in the AppSync 4.2 User Guide troubleshooting section, page 295.This process is also documented in the 4.5 User Guide page 351. This procedure should be done as the user that is used while adding the UNIX host to the AppSync. The procedure in the above noted manual states:You must set the ./acp -c systemctlDaemonReload="TRUE" variable through acp option in the Linux agent server from the AppSync install directory. To set the variable in the Linux agent server, use the settings file ./acp -c systemctlDaemonReload="TRUE". To confirm the setting, run "./acp -v" Per the same Documentation: To confirm the setting, run "./acp -v" from the install directory or open the /root/.appsync/settings.xml file.For sudo user, the location for the settings.xml file is /home/sudouser/.appsync/settings.xml.
