      Description

      I am using mongodb version v3.4.5, Storage engine - WiredTiger on

      Mongo db sever not starting due to unexpected shutdown.

      My issue is same as https://jira.mongodb.org/browse/SERVER-18448 and https://jira.mongodb.org/browse/SERVER-30942

      Dbpath = /var/lib/mongo
      OS = CentOS Linux 7 (Core) 64bit on Vmware
      Disk type = HDD
      Disk management = LVM
      Disk is working fine.
      RAID = RAID not configured.

      I have used below --repair order to repair it, this error message show. I have attached other required information with WiredTiger files. Can you help me fix this problem?
