[knot-dns-users] Knot 2.4.1 on CentOS 7

Hi All, I built Knot 2.4.1 rpm and tried it on CentOS7. The server isn't reading any of our zones with an error of: "failed to load persistent timers (invalid parameter)" Therefore it won't accept any notifies form master and won't read or transfer any zone. Even when I do "knotc refresh ZONE" it will fail saying zone is unknow. This is an upgrade from Knot 2.2, and same configs doesn't complain about anything and the server starts fine using that version, and load zones, and respond to DNS queries without a problem. I tried to find a procedure for a first time install for Knot and see if there is any required initialization that needs to be done but no luck. Have anyone tried Knot 2.4.1 with CentOS 7 please and successfully had it running? Note that I tried: knotc conf-check (responds with: Configuration is valid) knotc conf-read (shows all zones and template configs being read and doesn't show any warning or error) knotc conf-init knotc conf-import /etc/knot/knot.conf Either one of those will generate confdb. However, conf-init generates it but then Knot doesn't show anything in the logs (set to debug), but does generate timers folder. But conf-import show same logs with same errors above, and still won't load any of our zones. I'm using these template settings: "" mod-rrl: - id: default rate-limit: 200 # Allow 200 resp/s for each flow slip: 2 # Every other response slips template: - id: default storage: /var/lib/knot/zones journal-db: journals timer-db: timers zonefile-sync: 60 semantic-checks: on global-module: mod-rrl/default "" I'd appreciate any suggestion please. I'm new to this list, so if this is not where I was suppose to send this please accept my apologize. Thanks, Kareem. -- Abdulkareem H.
