HDD hibernate in logs

[Charlie Brown]

I would like to know when the HDD hibernate and/or wake up.

Hi Charlie,

Thanks for the great suggestion!!! I will feedback your suggestion to our product development team and see if it is feasible to add this into logs and if this resource consumption, frequency of logging will be acceptable!

[Charlie Brown]

Thanks! With a minimum interval of 5 minutes I fail to see how this could become a resource problem.

I would like to see status, rather than a log. It's helpful if we know which processes occupy HDD to prevent HDD hibernation. A log in HDD could result in HDD working all the time and the huge information (HDD accessing) is not easy to read.

Hibernate routine:

1. Write log.
2. Hibernate

HDD wake up routine:

1. Wake HDDs
2. Write log

mm... As far as I know, SATA HDD supports standby timer. It means HDD will go to standby (hibernation) mode automatically (the timer duration can be set by hdparm). Writing log will result in HDD working all the time if asustor implements this way. If they create a process to do hibernation task, the way you suggested is possible. However, I believe they should utilize hdparm.

Hi Charlie an Orion,

After discussion internally, we do utilize the hdparm and writing log will result in the hdd timer to be reset and preventing the hard drive from sleeping. We will keep on thinking of other possibilities. Any idea is welcome!

Bummer. Final idea is to check out Synology/XPEnology code as they are able to do this.

I searched the log in my Synology DS1511 (3 drives installed) but did not find the log of hard drive going to sleep. Do you mean that I have to replace DSM with XPEnology? And which package to install?

[Charlie Brown]

I am in error and stand corrected. On Synology it is only logged when the HDD's wake up, not when they are going into hibernate.
Still very useful if one wants to know how many times the drives wake up. Perhaps this is feasible Shawn?
