[Gluster-users] nfs

[Paul Cuzner]

Hi John, 

I think on gluster 3.3 and 3.4, nfs is enabled by default. 

nfs is actually a translator, so it's in the 'stack' already - this is why you don't need the nfs-kernel-server package. 

When mounting from a client, you just need to ensure the mount options are right 
i.e. use the following -o proto=tcp,vers=3 (for linux) 

The other consideration is that by default the volume will expose 64bit inodes - if you have a 32bit apps, or OS you'll need to tweak the gluster volume with "vol set <vol> nfs.enable-ino32 on" 

I haven't got a 3.3 system handy, but on a 3.4 system if you run the following 
gluster vol set help | grep "^Option: nfs." 

you'll get a view of all the nfs tweaks that can be made with the translator. 

Cheers, 

Paul C
