Issue

  • In the course of a DR scenario, clients attempting to mount an NFS export encounter access denied by server while mounting
  • While the client hostnames stay the same, their IP addresses will change post-failover (especially if DHCP is in use)
  • The export policy rules govern client access by hostname rather than IP
  • MGWD log shows Authoritatively returning zero rules
