Cannot Mount NFS Export

Description

In order to write to this volume, replication must be
detached first. Refer the user to the correct location.
When attempting to mount an NFS export, the mount
command fails due to various reasons such as:
• Permission denied.
• appliance not responding due to port mapper
failure - RPC timed out or input/output error.
• appliance not responding due to program not
registered.
• Access denied.
• Not a directory.
• The client connects using NFS/UDP and there is a
firewall in the way.
• The client is not in the export list, the appliance
could not recognize the client system through
NIS, or the appliance does not accept the identity
you provided.
• The NAS cluster solution is down or has internal
file system problems.
• The mount command got through to the port
mapper, but the rpc.mountd NFS mount daemon
was not registered.
• Client system's IP address, IP range, domain name
or netgroup is not in the export list for the volume
it is trying to mount from the NAS appliance.
• Either the remote path or the local path is not a
directory.
• The client does not have root authority or is not a
member of the system group. NFS mounts and
unmounts are only allowed for root users and
members of the system group.
If the issue is due to NFS/UDP and firewall, check if the
client mounts using UDP (this is usually the default) and
there is a firewall in the path. If a firewall exists, add an
appropriate exception to the firewall.
If the issue is due to permissions:
• Verify the path you provided is correct.
• Check that you are trying to mount as root.
• Check that the system's IP address, IP range,
domain name or netgroup is in the exports list.
If the appliance not responding due to a port mapper
failure:
• Check the NAS cluster solution status.
