Hard Disk wake up very frecuently

[serram]

In Web Interface, at the section of "Disk Setup / Spin-down guard internal Hard Disk", the current setting is: enabled, Inactivity period 30 Minutes.
So sometimes I can see that the disk is sleeping, becouse I can´t hear nothing and there is no vibration on the box.

But many times, I realized that the disk wake up without aparently reason, becouse all the computers and players of the network are off. And I can hear the spin up of the disk and the low noise of the box, and this happens very frequently. At least 1 time by hour.

I'm using samba version 4.9.4, with smb1 disabled, and the only other server that I have installed is MiniDLNA.
Can be MiniDLNA the guilty of this situation?

SMART activated ?

SMART activated ?

Yes, acording the web interface...

Model: Seagate Barracuda 7200.14 (AF)
Device: ST2000DM001-1CH164
Smart status: Enabled
Health Test: PASSED

Then, do you think that the SMART function is the guilty of this situation?

In that case, and thinking in the disk health...
With the current settings the disk is doing a spin up and a spin down more than 30 times by day.
I guess that this is not a very convenient behavior for the disk health.

Things I can do:
1. Disable SMART function in order to achive that the disk remain still until there are access to the data on the disk.
I don't know how to do it, and I don't know if it's a recommended practice, to loose the warning of disk failure provided by the SMART function.
2. Disable the spin down during inactivity period in order to the disk remain always spining.
I can't find that the way to do it in web interface, and I don't know if this option is better for the disk health rather than the previous option.

The HDD is the original Seagate Barracuda 7200.14 (ST2000DM001-1CH164).

Any thoughts?

SMART isn't causing disk spin up. There must some activity in your LAN connecting to your NAS. To test you could disconnect LAN cable of the nas and see if spin up still occurs.

In my new combination Raspberry Pi4 with an external 8TB HDD SMART was exactly the problem why it never spinned down.
Switching off or drastically increasing the test periods solved that problem.

:scratch Afaik there is no possibility in fvdw-sl firmware interface to set a periodic check, only a health test, and a short and long test, see screenshot below.

Probably you did not use fvdw-sl firmware interface but you used hdparm commands to change default disk settings directly on the firmware of the disk
So where do you set smart test interval?
or how did you disable it ?

Hi

yes smartctl allows to disable SMART feature

Code: Select all

smartctl -s off /dev/sdN

Code: Select all

root@Acrab:/ # smartctl -s off /dev/sdd
smartctl 6.3 2014-07-26 r3976 [armv5tel-linux-5.4.16] (local build)

=== START OF ENABLE/DISABLE COMMANDS SECTION ===
SMART Disabled. Use option -s with argument 'on' to enable it.

Yes I know but it cannot be done using fvdw-sl webinterface.
Maybe good suggestion to add it

Usually it is not a good idea to disable SMART on a disk as without it you can not detect a pre-fail state
