[Gluster-users] Cann't mount NFS,please help!

[Erik Jacobson]

If you are like me and cannot yet switch to Ganesha (it doesn't work in
our workload yet; I need to get back to working with the community on
that...)

What I would have expected in the process list was a glusterfs process with
"nfs" in the name.

here it is from one of my systems:

root     57927     1  0 Mar31 ?        00:00:00 /usr/sbin/glusterfs -s localhost --volfile-id gluster/nfs -p /var/run/gluster/nfs/nfs.pid -l /var/log/glusterfs/nfs.log -S /var/run/gluster/933ab0ad241fab5f.socket


My guess - but you'd have to confirm this with the logs - is your gluster
build does not have gnfs built in. Since they wish us to move to
Ganesha, it is often off by default. For my own builds, I enable it in
the spec file.

So you should have this installed:

/usr/lib64/glusterfs/7.2/xlator/nfs/server.so

If that isn't there, you likely need to adjust your spec file and
rebuild.

As others mentioned, the suggestion is to use Ganesha if possible,
which is a separate project.

I hope this helps!

PS here is a sniip from the spec file I use, with an erikj comment for
what I adjusted:

# gnfs
# if you wish to compile an rpm with the legacy gNFS server xlator
# rpmbuild -ta @PACKAGE_NAME at -@PACKAGE_VERSION at .tar.gz --with gnfs
%{?_without_gnfs:%global _with_gnfs --disable-gnfs}

# erikj force enable
%global _with_gnfs --enable-gnfs
# end erikj
