Constant disk noise - anyway to check disk activity?

[jack]

Hi,

I have a TNAS F2-210. There has been constant disk noise since I swapped out the WD Reds and installed Seagate Ironwolf 4TB x 2, which wasn't there before with the WD drives. I can see the HDD indicators blinking at times, but not always. I tried to use the common disk activity tools like iotop, iostat, dstat, ioping, atop, etc. but it seems like none of them is supported. I was wondering how can I monitor the disk activity to see what's using the hard drives?

Thanks a lot!

Jack

in the wisdom terramaster actually install and run the OS from the hard drive so it will always be using some sort of hard drive usage even if no one is accessing it remotely

Maybe the hard disk is defective or this is just its characteristic.

SMART is good. Seagate Iron Wolf is recommended by TerraMaster as a low noise option.

Also, that's NOT the point. How can you monitor disk activity on TNAS? Considering it's a storage product, that's not too much to ask.

[TMSupport]

You can SSH access your TNAS as root, and enter the command dmesg to list the disk activity.

dmesg doesn't actually show what process is doing IO at what rate. Can you provide more information about how to assess that?

This command will show you the top 10 processes using CPU. That will at least give you an idea of what processes are actively doing something.

Code: Select all

ps -aux --sort -pcpu | head

Thanks, Jay!
