Something is going on on my NAS, but what is it?

Post by iMactouch » Wed May 02, 2018 4:04 am

Hi!

I have a TS-453A (4.3.4.0551 Build 20180413) with four WD RED 4TB drives running in a RAID-5. Also there is a VM running on an external USB-SSD which has normally one share of the NAS mounted.
The only things I installed is Virtualization station. HD Station is off, No SQL Server is running, no Syslog Server, no Antivirus, No whatever server.

But when the VM is not running and no shares of the NAS are mounted an no one is doing something on the NAS, the drives are still working.
This is going through the whole day. I don't know what to stop or kill to let the drives do nothing.

I did 10 runs of the blkdev script. Here is the output:
blkdevMonitor_v2.log.zip


I see that the raid itself is writing every time the same 1 sector. What is this?

A few versions of the firmware before the drives are completely quiet.

Can someone here help me?

I will send it this evening when I am at home.
Is "ps -ef" enough?
