> > I was having issues with elasticsearch now too since I rebooted my server.
I'm running Zammad on Centos and installed it as a Package. After the reboot the elasticsearch.log hit these errors: *[2017-06-14T16:31:12,424][ERROR][o.e.b.Bootstrap ] Exceptionjava.lang.IllegalArgumentException: plugin [mapper-attachments] is incompatible with version [5.4.1]; was designed for version [5.4.0] at org.elasticsearch.plugins.PluginInfo.readFromProperties(PluginInfo.java:146) ~[elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Spawner.spawnNativePluginControllers(Spawner.java:86) ~[elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:167) ~[elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:350) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:123) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:114) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:67) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:122) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.cli.Command.main(Command.java:88) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:91) [elasticsearch-5.4.1.jar:5.4.1]* *[2017-06-14T16:31:12,424][ERROR][o.e.b.Bootstrap ] Exceptionjava.lang.IllegalArgumentException: plugin [mapper-attachments] is incompatible with version [5.4.1]; was designed for version [5.4.0] at org.elasticsearch.plugins.PluginInfo.readFromProperties(PluginInfo.java:146) ~[elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Spawner.spawnNativePluginControllers(Spawner.java:86) ~[elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:167) ~[elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:350) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:123) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:114) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:67) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:122) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.cli.Command.main(Command.java:88) [elasticsearch-5.4.1.jar:5.4.1] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:91) [elasticsearch-5.4.1.jar:5.4.1]* So I checked: *cat /var/log/yum.log |grep elasticsearch* Output*:* *May 17 22:48:32 Installed: elasticsearch-5.4.0-1.noarchJun 01 21:45:25 Updated: elasticsearch-5.4.1-1.noarch* I did some updates recently and so I guessed I had to rollback. Luckily Centos offers an easy way to rollback packages so i did: *yum downgrade elasticsearch-5.4.0-1.noarch* followed by: *systemctl daemon-reload* *systemctl restart elasticsearch* The logs were fine after that and the search function works as usual. Perhaps I have to recreate the indexes but I have to dig into the manual on how to do that.
