What makes your FSAL not support NFSv4.1? From the perspective of a FSAL, most of 4.1 has nothing special about it other than PNFS, support for which is explicitly enabled by the FSAL.

I'm exploring 2 following options: 1/ A way to tell ganesha that we don't have export for 4.1 at init 2/ Return NOTSUPPORTED for one of the NFS message during mount stage (like PUTFH, GETATTR, etc). But related function in the fsal level do not have input param containing the minorversion. Can anyone give me a hint? Thank you

OK, there is a config for that… NSFV4 { Minor_Versions = 0; } It takes a list of allowed minor versions.

It is just because we have never tested our FSAL with 4.1 and our usual test suites pass partially so while waiting for the whole investigation, we'd like to prohibit 4.1 mount to avoid surprises. Is there any way to do that? Thanks On Tue, Nov 23, 2021 at 3:40 PM Frank Filz <ffilzlnx(a)mindspring.com <mailto:ffilzlnx@mindspring.com> > wrote: What makes your FSAL not support NFSv4.1?
