From: Kaleb Keithley [mailto:kkeithle@redhat.com] FSAL_XFS uses the fcntl that XFS provides instead of open_by_handle_at and name_to_handle_at. Thus it works on kernels too old to have those system calls. XFS offers a library that makes the fcntl calls. There are a few other differences but that's the main difference.

The question is if anyone needs the Lustre specific code that is used to make a separate FSAL_LUSTRE from FSAL_VFS. And then, if anyone needs it, is anyone willing to support the code? I have never used Lustre and could not support anything Lustre specific. Thanks Frank

Thanks for that. One thing that would help is more visibility. Is it possible to make the community calls? Tuesday’s 7:00 AM Pacific Time.

However, we have encountered issues preventing us from migrating to the latest stable v6.5, as our test suite for Ganesha currently passes only for v4.4 but not for v6.5 (21 / 23 pass successfully, 2 tests fail). In the coming days, I plan to update our GitHub Actions pipeline to run our test suite for Ganesha v6.5, making the results available to the Ganesha community. As part of the SaunaFS community, we are committed to support SaunaFS FSAL and keep it up to date with the latest API changes. From our team, we would like to contribute to ensure FSAL_SAUNAFS remains supported and compatible with the latest Ganesha versions.

Hi Frank and community, I wanted to share my perspective on the value of maintaining simpler FSALs like VFS or PROXY_V3. * These FSALs provide a consistent method for reproducing testing failures, which we've found useful in the past <https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1194944/comments/737906... . * They offer new users a straightforward way to begin testing (example <https://github.com/nfs-ganesha/nfs-ganesha/blob/afdc43ff7ae1daa91471bc485...>) and serve as a practical foundation for developing custom FSALs. Should we keep at least one of them? Thanks, Yoni On Sun, Apr 6, 2025 at 1:31 PM Ruben Alcolea <ruben.crash(a)gmail.com&gt; wrote:

Hi Frank, Sorry for the late reply. I saw some discussions about the FSAL_VFS (FSAL_VFS/xfs). Could we keep the FSAL_VFS as the supported label? I thought FSAL_VFS might be beneficial to some home lab users (including me). It was suitable for fast deployment in some scenarios. I am happy to spend some time rechecking the whole VFS code and make this more effective support. Thanks! Frank Filz <ffilzlnx(a)mindspring.com&gt; 於 2025年4月1日 週二 上午5:04寫道：
