Sorry for the confusion about FSAL_VFS and its sub FSALs.

FSAL_VFS is in no danger of going away, I run all my merge smoke testing with FSAL_VFS and most of my unit testing. It will continue to support pretty much any filesystem the kernel NFS server supports (other than maybe NFS re-export, but we have FSAL_PROXY_V3 and FSAL_PROXY_V4 for that).

What’s under discussion is:

FSAL_XFS – FSAL for XFS that does not depend on the not so new system calls open_by_handle_at and name_to_handle_at.

FSAL_LUSTRE – A modification of FSAL_VFS to add a bit more support for Lustre features.

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!

Community,

We have a number of FSALs in Ganesha that have no effective support, I’d like to understand who might still be relying on them and if there is anyone who might step up to support them, or whether we can consider removing some on an expedited timeline (normally we declare a FSAL is deprecated in one release, and then remove it in the next). Note that with the magic of git, deleted FSALs could easily be resurrected (though they might not have been updated to match API changes). The risk of not removing unsupported code is first that folks will use code with little or no support and open github issues that cannot effectively be addressed, and that unsupported code may not be properly updated as API changes are made.

The following FSALs are suspect:

src/FSAL/FSAL_VFS/xfs – this is marginally supported, but could be replaced with plain FSAL_VFS

src/FSAL/FSAL_VFS – there is also a Lustre FSAL that is built from this

src/FSAL/FSAL_GLUSTER

src/FSAL/FSAL_LIZARDFS

src/FSAL/FSAL_PROXY_V3

src/FSAL/FSAL_PROXY_V4

src/FSAL/FSAL_KVSFS

src/FSAL/FSAL_SAUNAFS

Thank for your thoughts

Frank Filz
