Identifying the Log File Associated with a Storage Pool

To determine the log file used by a storage pool, run the following command:

/opt/mapr/server/mrconfig sp list -v

Your output should look similar to the following:

# /opt/mapr/server/mrconfig sp list -v
ListSPs resp: status 0:4

The output above shows the following:

  • Four storage pools associated with two fileserver instances running on ports 5660 and 5661.
  • Port 5660 corresponds to mfs.log-3 files and port 5661 corresponds to mfs.log.1-3 files.
