      Hi Team,

      Thanks for your continuous support !!
      *We have a production issue as in , the journal data is not cleared till mongoServer is restarted!! This folder has reached approximately 75GB!!!!
      and occupied almost entire Drive !!!!
      We would like to here from you that*_,
      If MongoDB Server is never restarted , will the binary log data under data/db/journal will not be cleared ?
      What is the Max number of journal files or max sixe of journal folder allowed to be created under Journal folder ?
      [We undertood from journal file sixe is 100MB]

      Reference links
      We have gone through the site:*https://docs.mongodb.com/manual/core/journaling/*

      It has mentioned that
      +"A clean shutdown removes all the files in the journal directory. A dirty shutdown (crash) leaves files in the journal directory;
      these are used to automatically recover the database to a consistent state when the mongod process is restarted"+

      Above statement implies that journal folder will keep on growing and never gets cleared ,
      until ,

      • Mongo server is not restarted or
      • One has to perform clean shutdown
        Please Clarify and address the above mentioned query

      Thanks & Regards
      Sandeep KS
