Assignee: mfriedrich Status: Resolved (closed on 2014-06-12 20:06:28 +00:00) Target Version: 2.0.0 Last Update: 2014-06-12 20:06:28 +00:00 (in Redmine)

Having a distributed cluster setup it would be nice to specify a directory (of config files, e.g. commands, template services) which gets synchronized to all nodes of all zones.

Imho that should rather be a global zone being synced to all nodes, flagged with a configuration attribute like `global = true`. That way the configuration naming is not scattered with an additional global constant, and everyone may just use whatever zone name they prefer.

Having a zone marked as global which gets synchronized to all nodes sounds very good.

Using 2.0.0~beta2+icingasnap201406112056.8d344eb~wheezy the shared zone is sometimes created in /var/lib/icinga2/api/zones on the endpoint but no files got sychronized. Sometime even the directory does not exists.

Starting icinga I see

Couldn't find anything about the "shared" zone in icinga2.log or debug.log

On the master icinga21 the directory /var/lib/icinga2/api/zones/shared exists with all files.

The slaves don't have the shared zone configured. why?

icinga-migration commented 10 years ago

Updated by tobiasvdk on 2014-06-12 09:30:49 +00:00

Adding the "shared" zone definition on icinga21-ka results in the following error:

Implemented it the wrong way, and used the wrong cluster config, sorry.
