[Gluster-users] nfs-ganesha HA with arbiter volume

[Soumya Koduri]

Hi Tiemen,

One of the pre-requisites before setting up nfs-ganesha HA is to create 
and mount shared_storage volume. Use below CLI for that

"gluster volume set all cluster.enable-shared-storage enable"

It shall create the volume and mount in all the nodes (including the 
arbiter node). Note this volume shall be mounted on all the nodes of the 
gluster storage pool (though in this case it may not be part of 
nfs-ganesha cluster).

So instead of manually creating those directory paths, please use above 
CLI and try re-configuring the setup.

Thanks,
Soumya
