[FATAL][logstash.runner ] Logstash could not be started because there is already another instance using the configured data directory. If you wish to run multiple instances, you must change the "path.data" setting

Hello;

I try to run two pipelines together but When I launch my pipelines with the command :

bin/logstash --path.settings /etc/logstash

I've got this error :

[FATAL][logstash.runner ] Logstash could not be started because there is already another instance using the configured data directory. If you wish to run multiple instances, you must change the "path.data" setting.

Do you know why i've got this issue ?

My /etc/logstash/pipelines.yml file :

- pipeline.id: pre_traitement
  path.config: "/etc/logstash/conf.d/pre_traitrement_vega.conf"

- pipeline.id: post_traitement_ironport
  path.config: "/etc/logstash/conf.d/fusion_vega_ironport.conf"

My /etc/logstash/conf.d/pre_traitrement_vega.conf file :

input

  file
  {
    path => "/data/IFR/ELK/work/FLD_PROD_UEM/*.log"

  }
  stdout { codec => rubydebug }
}

My etc/logstash/conf.d/fusion_vega_ironport.conf file :

  }
}

  #huge filter

      index => "ironport"
    }
    stdout { codec => rubydebug }
  }
  else if [filetype] == "VegaProdUEM"

      #hosts => "https://localhost:9200"
      index => "vegaproduem"
    }
    stdout { codec => rubydebug }
  }
}

But when I restart my logstash service and I launch quickly my pipeline, it works...

Thx for help

Are you saying you are running it as a service and also running it using the command line?
