Hi Nico,
The option is ganesha-server specific option(not per export). U need to mention it in ganesha.conf in the following block
NFSv4 {
minor_versions = 1;
}
Not inside the block of block of volume configuration file

Subject: Restricting NFS-Ganesha to use NFSv4.0 only
Hi All,
In a bugzilla ( https://bugzilla.redhat.com/show_bug.cgi?id=1546713 ) I was reading it showed that it should be possible to restrict the NFSv4 usage to only use 4.0 (since 4.1/4.2 is not supported).
To try that, I modified an existing share so it reads :
EXPORT{
Export_Id = 2;
Path = "/DATA";
FSAL {
name = GLUSTER;
hostname="localhost";
volume="DATA";
}
Access_type = RW;
Disable_ACL = true;
Squash="No_root_squash";
Pseudo="/DATA";
Protocols = "4" ;
Transports = "UDP","TCP";
SecType = "sys";
NFSv4 {
minor_versions = 0;
}
}
And restarted the nfs- ganesha service. Seemed to start fine and mounted the share from a client and specifying the mount option "-o vers=4.1" and indeed it mounted it with NFSv4.1 (I was expecting/hoping it would refuse to mount).
What is (or should be) the way to only allow NFSv4.0 exports (if possible at all) ?
Running GlusterFS 3.12 / RHGS 3.4 with packages :
