Hi,
first of all, I've modified the corresponding workflow once again, because there was some none unique sql queries within the parent volume command.
so please use the attached WF .. regarding the /etc/exports, I've checked that in my envrionment and the new export definitions will extend the existing config file.
but my suggestion would be to test the WF in your test envrionment and afterwards on your production systems.
have fun, thx and regards Jens
