      Snort 2.9.5.6 pkg v3.0.6 and using snort pfsync settings to keep the secondary updated.

      I just upgraded my secondary cluster member to 2.1.2 and barnyard somehow is enabled now.  The primary still shows barnyard as disabled for both LAN and WAN.

        I forgot to disable sync before upgrading the secondary so it might have something to do with the secondary is running a different version of snort now than the primary.  Both the primary and secondary had Snort 2.9.5.6 pkg v3.0.4 before the upgrade of the secondary.  In the future I should make sure to disable sync before upgrading and then enable sync after both systems are upgraded (I forgot to do that) just in case this is related to config differences or something between snort versions (just a wild guess that might be the issue).

        I bet it will get fixed when I upgrade the primary and the primary syncs the same version of snort config over that the secondary is running.  We shall see.

        EDIT: To be clear… I have never enabled barnyard on any of the systems.

          Upgrade of the primary… Now the primary has barnyard enabled for both LAN and WAN too.  Not sure what is causing this.  Not a big deal though.  I just disabled it on the primary for both instances and the backup server got the synced snort config and is disabled there now too.

            There was a little logic error I introduced into the Barnyard2 migration code that migrates old settings into the new format to support the enhanced output plugins.  I was keying off only one of two parameter that must BOTH be true for Barnyard to have been enabled under the old config.  As a consequence of only looking at one and not both, the migration script was turning on Barnyard2 if it had ever been enabled in the past on an interface.

            I am fixing that for future upgrades, but for this one the damage is sort of done.  Thankfully it's not a fatal thing.  Just disable Barnyard2 on the interface again and save the update.

            There are some problems with updating synced pairs with sync still on.  I recommend turning off sync, upgrading all the machines to the same version, then re-enable sync.
