It would be nice to know why you cannot use ganesha or mmsmb. You don't have to use protocols or CES. We are migrating to CES from doing our own thing with NFS and samba on Debian. Debian does not have support for CES, so we had to roll our own. We did not use CNFS either. To get to CES we had

What do you mean by cannot use mmsmb and cannot use Ganesha? Do you functionally you are not allowed to or they are not working for you? If it's the latter, then this should be resolvable. If you are under active maintenance you could try raising a ticket with IBM, though basic implementation

Under the hood, the NFS services are provided by IBM supplied Ganesha rpms. It's then fully supported by IBM, e.g. the GPFS VFS later to handle locking, ACLs, quota etc... Note it's different from using the cnfs support in Spectrum Scale which uses Kernel NFS AFAIK. Using user space Ganesha

Hi guys, I see IBM spectrumscale configure the NFS via command: mmnfs Is the command mmnfs is a wrapper on top of the normal kernel NFS (Kernel VFS) ? Is it a wrapper on top of ganesha NFS ? Or it is NFS implemented by SpectrumScale team ? Thanks -- - Ilan Schwarts
