Hello! Decided to set up balancing through dns on a cluster of two pairs FAS3220. Accordingly, the name server runs on Bind 9 version. Accordingly, under the instruction through the slave zone does not work, gives 'refused message' when attempting to copy it from NetApp. In a direct appeal to the address nslookup lif successfully issued the zone name, but only two of the four nodes, and the rest do not respond and for some reason are not available on 53 port. Help me please with configuration problems... Thank you!
