[/] # find / -name vg*.log
/mnt/HDA_ROOT/.config/storage_usage_history/vg1.log
/mnt/HDA_ROOT/.config/storage_usage_history/vg2.log
[/] # cd /mnt/HDA_ROOT/.config/storage_usage_history
[/mnt/HDA_ROOT/.config/storage_usage_history] # ls -l
-rw-r--r-- 1 admin administ 16686 Apr 19 01:40 CACHEDEV2_DATA.log
-rw-r--r-- 1 admin administ 16046 Apr 19 01:40 vg1.log
-rw-r--r-- 1 admin administ 16634 Apr 19 01:40 vg2.log

Which, if the disk is being written to - would explain why this is being logged (as it's usage).

Surely this will prevent the disk from spinning down, as writing the disk update history to the disk will spin up the disk, and this disk I/O to the logs will trigger writing a further history update after 10 minutes, etc., etc.

I just rechecked the log1.log and log2.log files that you produced yesterday to see if the same thing was happening. The log2.log file (wthout MinimServer running) was truncated by Ctrl-C at the 9/100 stage, but the log1.log file was allowed to terminate normally after completing the final 99/100 test. This could explain why log2.log is much smaller than log1.log.
