I just added a slave of a master for disaster recovery and now need to know how
to promote it should the master be offline too long. What I have found so far
is:
1. For the zone definitions in /etc/named.conf (or equivalent):
(a) Change the “type” statements from ”slave” to “master” and remove the
“masters” statement.
(b) Add “allow-update” and “allow-transfer” statements as appropriate.
(c) Possibly add “also-notify” statements as appropriate.
2. Add key definitions if needed
3. If “masterfile-format text” wasn't used in named.conf.local convert the zone
files to text using named-compilezone including the -j parameter.
4. If the server's name is different than the former master then the SOA record
for each (to be ) master zone must be updated. Since rndc
freeze/thaw doesn't work on slave zones the server probably needs to be
shut down.
5. Change the MNAME to the new server name
Anything I've missed? Thanks for your help. I also have a question about DNS
and keepalived but I'll make that another post.
