[SOLVED] Disk spun down while in use?

[ash.881]

It appears a disk spun down while in use and I have no idea why.

 

The only reason I noticed is because I have just installed an auto sleep script and the server went to sleep while I was watching something.

 

It looks like the drives have all spun down (even the one in use) and then the script has kicked in like it's supposed to once all drives were spun down.

 

But the question is why did Unraid spin down a drive while it was in use??

 

Parity is set to spin down after 15 mins, the 2 data drives are set to 30mins.

 

Syslog is attached (spindown is @ 15.31.22), copy of sleep script is attached (though I don't see anything wrong with it).

 

Version: Unraid 4.7

If all the data needed for the movie was in memory already there will be no disk accesses. (in other words, it could go to sleep, especially with such a short spin-down delay.)

One possible logic flaw is that the disk devices can change from one boot to another.  It is possible the disk with the media you were watching was not sda, sdb, or sdc.

 

It is better if you list the devices by their names as found in /dev/disk/by-id instead of /dev/sda, etc.

You could use "/dev/sd?"

You could use "/dev/sd?"

probably not without additional logic as that would include the flash drive... and they do not sleep.
