My Admin guide says: The loss percentage and period are set via the configuration variables fileHeatLossPercent and fileHeatPeriodMinutes. By default, the file access temperature is not tracked. To use access temperature in policy, the tracking must first be enabled. To do this, set the two configuration variables as follows: fileHeatLossPercent The percentage (between 0 and 100) of file access temperature dissipated over the fileHeatPeriodMinutes time. The default value is 10. Chapter 25. Information lifecycle management for IBM Spectrum Scale 361 fileHeatPeriodMinutes The number of minutes defined for the recalculation of file access temperature. To turn on tracking, fileHeatPeriodMinutes must be set to a nonzero value. The default value is 0
SO Try setting both! ALSO to take effect you may have to mmshutdown and mmstartup, at least on the (client gpfs) nodes that are accessing the files of interest. From: Ulrich Sibiller <u.sibil...@science-computing.de> To: gpfsug-disc...@gpfsug.org Date: 08/12/2019 06:50 AM Subject: [EXTERNAL] [gpfsug-discuss] Fileheat Sent by: gpfsug-discuss-boun...@spectrumscale.org Hello, I am having difficulties with Spectrum Scale's fileheat feature on Spectrum Scale 5.0.2/5.0.3: The config has it activated: # mmlsconfig | grep fileHeat fileHeatPeriodMinutes 720 Now everytime I look at the files using mmapplypolicy I only see 0 for the fileheat. I have both tried reading files via nfs and locally. No difference, the fileheat always stays at zero. What could be wrong here? How to debug? We are exporting the filesystem using kernel NFS which is working fine. However, the documentation states that root access is not taken into account for fileheat, so I am wondering if that setup is supposed to work at all?
