Thanks Christof. The usecase is just that : it is easier to have symlinks of files/dirs from various locations/filesystems rather than copying or duplicating that data.
The design from many years was maintaining about 8 PB of NFS filesystem with thousands of symlinks to various locations and the same directories being exported on SMB. Now we are migrating most of the data to GPFS keeping the symlinks as they are. Thus the need to follow symlinks from the GPFS filesystem to the NFS Filesystem. The client wants to effectively use the symlinks design that works when used on Linux but is not happy to hear that he will have to redo years of work just because GPFS does not support the same. I understand that there might be a reason on why CES might not support this, but is it an issue if we run SMB server on the GPFS clients to expose a read only or read write GPFS mounts?
