NFS Mount Fails Due to Export Options

Description This event is issued when an NFS mount fails due to export options.
Cause The export list filters client access by IP address, network, or netgroup, and screens the accessing client.
Workaround
  1. Verify the relevant NFS export details. Write down all existing options so that you are able to revert to them.
  2. Remove IP address/client restrictions on the NFS export and retry the mount. If the mount succeeds, verify that the IP address or domain is explicitly specified, or that it is part of the defined network or netgroups. Once the mount succeeds, adjust the original options accordingly.

    Pay attention to pitfall scenarios, where the network netmask is not intuitive, for example, 192.175.255.254 is part of 192.168.0.0/12 but not of 192.168.0.0/16.
