Edit - Correction, the master node is working, but the storage node still doesn’t mount…

Am I mistaken, or was the problem exactly the opposite before?

You are half right :), the nodes have swapped, but before was a “connection refused”, not it’s “operation not supported”

Both nodes are back online now. I had a left over “-T” in /etc/default/nfs-kernel-server on the storage node from my attempts to disable NFSv4. What I was reading said NFSv3 doesn’t use TCP and is only UDP. Well, however fog connects it needs TCP with v3.

Here is where I ended, I don’t know if the RPCNFSCOUNT of 48 is needed to be increased from the default 8, but I read that this increases the threads for nfs workers.

/etc/default/nfs-kernel-server

# Number of servers to start up
# To disable nfsv4 on the server, specify '--no-nfs-version 4' here
RPCNFSDCOUNT='48 --no-nfs-version 4'

# Runtime priority of server (see nice(1))
RPCNFSDPRIORITY=0

# Options for rpc.mountd.
# If you have a port-based firewall, you might want to set up
# a fixed port here using the --port option. For more information,
# see rpc.mountd(8) or http://wiki.debian.org/SecuringNFS
# To disable NFSv4 on the server, specify '--no-nfs-version 4' here
RPCMOUNTDOPTS='--manage-gids --no-nfs-version 4'

# Do you want to start the svcgssd daemon? It is only required for Kerberos
# exports. Valid alternatives are "yes" and "no"; the default is "no".
NEED_SVCGSSD="no"

# Options for rpc.svcgssd.
RPCSVCGSSDOPTS=""

# Options for rpc.nfsd.
RPCNFSDOPTS=""

# If you do not set values for the NEED_ options, they will be attempted
# autodetected; this should be sufficient for most people. Valid alternatives

# Do you want to start the statd daemon? It is not needed for NFSv4.
NEED_STATD=

# Options for rpc.statd.
#   Should rpc.statd listen on a specific port? This is especially useful
#   when you have a port-based firewall. To use a fixed port, set this
