My Admin guide says:
The loss percentage and period are set via the configuration

the two
configuration variables as follows:*
Yes, I am aware of that.
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!
Well, I have not because the documentation explicitly mentions a default. What's the point of a
default if I have to explicitly configure it?
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.
I have now configured both parameters and restarted GPFS. Ran a tar over a directory - still no
change. I will wait for 720minutes and retry (tomorrow).
Thanks
