Hi guys, I'm an intern at my software engineering company adding a health endpoint (using Spring Actuator) to our API for our Elasticsearch service. I am using POSTMAN to view the JSON response and it's sending it correctly, but listing Elasticsearch as "OUT\_OF\_SERVICE": ![38%20AM](https://us1.discourse-cdn.com/elastic/original/3X/3/4/347e3ecac543d77f50854c40b1ef89161416569d.png) Upon further inspection, I found when I boot up ./elasticsearch from local on the terminal (Mac) , it is throwing some errors for "failed to recover translog" , which another developer indicted to me might be the issue. It's a pretty big log. Is there a way to upload or copy and paste it here to get some help? I would like to avoid having to reinstall Elasticsearch if its a minor fix. Anyhelp would be greatly appreciated ---

Here is just some of the output , but I can copy and paste the entire thing if need be: ![29%20AM](https://us1.discourse-cdn.com/elastic/original/3X/4/9/492e26c6b8b722f71ba508648bf66208630a9012.png) ---

Also, after some googling , I managed to find other people with similar issues (corrupted trans logs?) and found this link on one of the threads: [https://www.elastic.co/guide/en/elasticsearch/reference/6.3/index-modules-translog.html#corrupt-translog-truncation](https://www.elastic.co/guide/en/elasticsearch/reference/6.3/index-modules-translog.html#corrupt-translog-truncation) However , when running the command : ` $bin/elasticsearch-translog -d /var/lib/elasticsearchdata/nodes/` .. I get this output in terminal: `ERROR StatusLogger No Log4j 2 configuration file found. Using default configuration (logging only errors to the console), or user programmatically provided configurations. Set system property 'log4j2.debug' to show Log4j 2 internal initialization logging. See https://logging.apache.org/log4j/2.x/manual/configuration.html for instructions on how to configure Log4j 2` `A CLI tool for various Elasticsearch translog actions` ``` Commands -------- truncate - Removes corrupted shard files Non-option arguments: command Option Description ------ ----------- -h, --help show help -s, --silent show minimal output -v, --verbose show verbose output ERROR: d is not a recognized option ``` ---

OK, I ran the command again and changed the directory but now getting an exception: `$ bin/elasticsearch-translog -d ~/documents/elasticsearch-6.7.0/data/nodes/` Exception that outputs after running the truncate translog tool: ``` Exception in thread "main" ElasticsearchException[index directory [/Users/Pizano_Alberto/documents/elasticsearch-6.7.0/data/index], must exist and be a directory] at org.elasticsearch.index.shard.RemoveCorruptedShardDataCommand.findAndProcessShardPath(RemoveCorruptedShardDataCommand.java:147) at org.elasticsearch.index.shard.RemoveCorruptedShardDataCommand.execute(RemoveCorruptedShardDataCommand.java:297) at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) at org.elasticsearch.cli.MultiCommand.execute(MultiCommand.java:77) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) at org.elasticsearch.cli.Command.main(Command.java:90) at org.elasticsearch.index.translog.TranslogToolCli.main(TranslogToolCli.java:39) ``` ---
