Thanks Stephen, Yes i do acknowledge, that it will need a SERVER license and thank you for reminding me.
I just wanted to make sure, from the technical point of view that we won’t face any issues by exporting a GPFS mount as a SMB export. I remember, i had seen in documentation about few years ago that it is not recommended to export a GPFS mount via Third party SMB services (not CES). But i don’t exactly remember why.
