Spindowns are easy to handle when they are software triggered. I do not think they are logged when the spindown happens at the drive level without being initiated from software. I am not sure that spin-ups generate events that can be logged. It may even be handled at the hardware level and not even visible at the software level. I would love to be proved wrong, though, as having spinups logged would be useful for investigating certain issues.
October 30, 20187 yr Author I do have those issues since 6.6.3. All drives spin up together many times a day. I did remove all plugins to test, without success. I did remove all Dockers to test, without success. I do see the system and/or emhttp to hang for a minute or so. After that all disks are spun up. Usually my systems run for months. Since 6.6.3 I'm rebooting daily. Perhapsa spinup log entry would help.
