26f327f1f53afdb8256affa1c197ed138bf3cb2fAndreas Gustafsson The best solution to solving installation and
ab023a65562e62b85a824509d829b6fad87e00b1Rob Austein configuration issues is to take preventative measures by setting
4bed2e84a34b37259b85e5c092d51c122ef58c3cBob Halley up logging files beforehand. The log files provide a
4bed2e84a34b37259b85e5c092d51c122ef58c3cBob Halley source of hints and information that can be used to figure out
4bed2e84a34b37259b85e5c092d51c122ef58c3cBob Halley what went wrong and how to fix the problem.

4bed2e84a34b37259b85e5c092d51c122ef58c3cBob Halley Zone serial numbers are just numbers — they aren't
ab023a65562e62b85a824509d829b6fad87e00b1Rob Austein date related. A lot of people set them to a number that
4bed2e84a34b37259b85e5c092d51c122ef58c3cBob Halley represents a date, usually of the form YYYYMMDDRR.
4bed2e84a34b37259b85e5c092d51c122ef58c3cBob Halley Occasionally they will make a mistake and set them to a
4bed2e84a34b37259b85e5c092d51c122ef58c3cBob Halley "date in the future" then try to correct them by setting
3740b569ae76295b941d57a724a43beb75b533baBob Halley them to the "current date". This causes problems because
94e25967cda41b886e33ec254b917d21df21a187Bob Halley serial numbers are used to indicate that a zone has been
94e25967cda41b886e33ec254b917d21df21a187Bob Halley updated. If the serial number on the slave server is
0a7bde9fa807f2e84bd7417d928581f40194b007David Lawrence lower than the serial number on the master, the slave
6fa1cb5754695d550a58c6e8978fda65f5146af7David Lawrence server will attempt to update its copy of the zone.
94e25967cda41b886e33ec254b917d21df21a187Bob Halley Setting the serial number to a lower number on the master
27809a2ee5db141b684e53bf1d94da26e9f92d3aMark Andrews server than the slave server means that the slave will not perform
afdb3abb9b06ed4070ac9021f1f4427b4cb3a286Bob Halley updates to its copy of the zone.
ab023a65562e62b85a824509d829b6fad87e00b1Rob Austein The solution to this is to add 2147483647 (2^31-1) to the
66d720025d9691b54bb2053850f73751986d5d57Mark Andrews number, reload the zone and make sure all slaves have updated to
66d720025d9691b54bb2053850f73751986d5d57Mark Andrews the new zone serial number, then reset the number to what you want
2cc9a6a0f79b56e36925845cad6d1ce41e4a1421David Lawrence it to be, and reload the zone again.
