[Darshan-users] Logs not generated inspite throwing warning message

[Harms, Kevin]

Hassan,

  did you create the  /darshan-logs directory? Looks like it might not be writeable.

  try: /darshan-logs/2021/6/21

  if you want to try a quick test, set DARSHAN_LOGFILE to the path/name of the log, like:

  DARSHAN_LOGFILE=/path/I/can/write/to/logfile.darshan

I am running darshan with mpich on a three-node cluster and my job executed successfully but not generated logs. error warning is given below at the end of the execution.
