Werk #12828: Distributed setup: Fix parallel activations breaking remote sites
|Titel||Distributed setup: Fix parallel activations breaking remote sites|
|Checkmk-Editon||Checkmk Raw (CRE)|
|Kompatibilität||Kompatibel - benötigt kein manuelles Eingreifen|
Previous 2.0.0 versions could break the Checkmk configuration on remote sites when two users tried to activate changes for a single remote site at the same time.
This was a race condition between both processes. While the first activation performed the synchronization to the remote site, the second activation could modify the files that are currently being synchronized by the first process. This could lead to incomplete configurations on the remote site.
Since the first activation did not know anything about this inconsistency, it tried to activate the incomplete configuration on the remote site after the sychronization which could fail with different error messages depending on which files were not transfered.
This issue only affected the configuration of remote sites. No configuration was lost on the central site.
If you want to prevent this issue with previous 2.0.0 releases, you need to ensure that you don't start two activations for a site at the same time.Zur Liste aller Werks
