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

hosts cobalt & iron are the data nodes, the arbiter ip/hostname (neon)
isn't mentioned anywhere in this config file.

Please send the /etc/ganesha/ganesha-ha.conf file you're using.
Probably you have included the arbiter in your HA config; that would be
a mistake.
