Hi! I just experienced an outage where a zone is defined via catalogzone and the following is set: SOA Refresh 900 SOA Retry 300 SOA Expiry 3600 (i'm aware it's very short)
Primary was intermittently unreachable and had wrong config for about 1.5h. According to logs the Secondary was retrying transfer every 7-8minutes as expected until the zone expired, after it expired it seems like it tried a couple times more then stopped trying for many hours. The only related config parameters i find are min-retry-time (default 5min) and max-retry-time (default 2 weeks) but there seems to be no mention if this is also related to the unreachability-cache for a certain master, or if this cache-time is even configurable. Now i wonder: Did it actually stop trying for many hours or was it retrying silently behind the scenes? If it did stop trying for many hours, how / where is this behavior defined (so i can learn to understand it) and can i cap it to retry failed zonetransfers at max X minute intervals if master is unreachable? 18:20:27 named: zone xx.yy/IN: expired 18:20:27 named: zone xx.yy/IN: refresh: skipping zone transfer as master aa.bb.cc.dd#53 (source 0.0.0.0#0) is unreachable (cached) 18:21:25 named: zone xx.yy/IN: refresh: skipping zone transfer as master aa.bb.cc.dd#53 (source 0.0.0.0#0) is unreachable (cached) 18:23:03 named: zone xx.yy/IN: refresh: skipping zone transfer as master aa.bb.cc.dd#53 (source 0.0.0.0#0) is unreachable (cached) 18:27:20 named: zone xx.yy/IN: refresh: retry limit for master aa.bb.cc.dd#53 exceeded (source 0.0.0.0#0) 18:34:53 named: zone xx.yy/IN: refresh: retry limit for master aa.bb.cc.dd#53 exceeded (source 0.0.0.0#0) 18:48:01 named: zone xx.yy/IN: refresh: retry limit for master aa.bb.cc.dd#53 exceeded (source 0.0.0.0#0) 18:50:19 named: zone xx.yy/IN: notify from aa.bb.cc.dd#54418: no serial 18:50:20 named: zone xx.yy/IN: refresh: skipping zone transfer as master aa.bb.cc.dd#53 (source 0.0.0.0#0) is unreachable (cached) 19:33:00 named: zone xx.yy/IN: notify from aa.bb.cc.dd#58236: no serial 19:33:00 named: zone xx.yy/IN: refresh: skipping zone transfer as master aa.bb.cc.dd#53 (source 0.0.0.0#0) is unreachable (cached) 19:59:42 named: zone xx.yy/IN: notify from aa.bb.cc.dd#50608: no serial 19:59:42 named: zone xx.yy/IN: refresh: skipping zone transfer as master aa.bb.cc.dd#53 (source 0.0.0.0#0) is unreachable (cached) 23:39:42 named: zone xx.yy/IN: sending notifies (serial 42) /Oskar -- Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.
