* EDIT 1 *
After monkeying with additional debug logging I see some log entries of interest.
27-Jul-2012 23:45:26.537 general: error: zone example.lan/IN/internal: journal rollforward failed: no more
27-Jul-2012 23:45:26.537 general: error: zone example.lan/IN/internal: not loaded due to errors.
^^^ If I can remedy the above messages I think I'll be good to go ^^^
* EDIT 2 *
Grasping at straws I touched a forward and a reverse zone journal file and restarted named. Boom! Works. Despite documentation stating the files are created automatically and what I have seen before... dunno why but that did the trick. Also re-checked perms on the dir the files live in. As certain as I was, they were correct with named having rw.
CentOS 6 (final)
dhcpd 4.1.1-P1
named BIND 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6
Basic DHCP and DNS functionality are in place on 192.168.111.2. Clients are assigned addresses as intended and can resolve local DNS names as well as Internet names. My problem is that named's zone journal files are not created.
chroot: /var/named/chroot
I tried placing the zone files in various directories (/var/named/data, /var/named, /var/named/dynamic - no matter which dir with named owning and wide open perms I now get nowhere). Along the way I, at one point, got a permission denied when named tried to create the journal. Resolved the issue by:
chown --recursive named:named /var/named
chmod --recursive 777 /var/named
The journal was then created and here's where things fell apart. I attempted to tame permissions to something more sane and broke it. Once changed and having restarted named it threw an error indicating the journal was out of sync (or something to that affect)... didn't matter since this is a new setup so I deleted it and now it is not recreated. Now though I see no errors in /var/log/messages, my chrooted /var/log/named.log, or chrooted /var/log/named.debug. I increased the debug level with 'rndc trace' - no love. Increased trace to 10, still nothing.

What can I do to troubleshoot this further? It almost seems as though dhcpd is not triggering the update. Maybe I should troubleshoot here and, if so, how?
Many thanks.
