Disk activity every 7-8 seconds (AS6204)

[nero78]

I have the new as6204 and i noticed that it constant as accessing the disk every 7-8 second even when there is no activity on the network or the NAS. How come? Very irritating when you have the NAS in your bedroom and unnessicary wear and tear on the hdd's...

I think it's caused by disk monitoring process to check if disk is idle or not. The check does not do disk physical access.

I setup system with single disk, and setup data volume on the other disks with RAID. My system disk does not go to idle state, but the other disks will go to idle state (LED will blink very slowly). That could save power.
Anyway, I did not check which processes make my system disk wake up all the time. I'm fine with it.

Asustor has very good night mode for LED. You can set it in Setting/Hardware/System.

I does do physical access. I can hear the disks clicking... How can i check the disk monitoring process?

Then it should be caused by certain processes. I guess the disk monitoring process is actually checking disk state by the linux command: hdparm. However I believe you are trying to find which processes are accessing disks all the time, rather than disk monitoring process, isn't it?
