NFS Ganesha as a Caching NFS Proxy
Hi All, Can we use FSCache or any other caching mechanism to first locally cache an NFS Filesystem, before re-exporting it using NFS-Ganesha? NFS Server ---> ((NFS Client SSD Cache + NFS Ganesha)) ---> Actual NFS ClientS Regards, Indivar Nair

I'm not sure. There's definitely issues with exporting an NFS mount via Ganesha (use FSAL_PROXY instead). I'm not sure if the local cache FS will fix those issues. Maybe it's worth trying? In principal, you can export any FS that is sufficiently like a local POSIX filesystem (which a local NFS mount is not). Daniel

There has also been talk in the past of reviving Ganesha's data cache in the form of a stackable FSAL, but that would be a modest development effort and depend on someone prioritizing development time. Frank
Okay. Ganesha NFS as an intermediate caching server would have lot of applications. Thanks Daniel Gryniewicz, Frank Filz, Regards, Indivar Nair
