How to fix BIND's journal out of sync error
If you are running a BIND name server with an dynamic zone updating from from DHCP or similar, you'll find that if the zone is manually updated the zone will no longer load correctly, giving the following error:
zone example.com/IN: journal rollforward failed: journal out of sync with zone zone example.com/IN: not loaded due to errors.
The error can be clearing seen by running BIND from command line as follows:
To resolve this stop BIND, then remove the journal file for problem zone, these exist in the same directory as the zone files but end in ".jnl". Once the file has been deleted BIND can be restarted and all will be back to normal.
If you have dynamic zones it is best to "freeze" them first before editing and "thaw" them after to avoid this problem in the first place. The commands for this are:
rndc freeze example.com
(edit example.com zonefile)
rndc reload example.com rndc thaw sxample.com
