HOW to know if disk are spinning or idle?

raulfg3 · 3. Januar 2014

Is there a command or something that can check disk status without disturbing ( if are spin down that continue spin down), and if exist, can de add to Disk Status to see temp and status (idle, spinning, sleeping, etc...)

You can see the temperature in the OMV WebUI:

Via command line you can do everything else. As you can see in the screenshot above, my data drives are sda, sdb, sdc and sdd. System is sde.
You can check the drive state (letters between those to [ ] are the ones you get data from. If you have more, feel free to add more letters)

Code

root@SJOMV:~# hdparm -C /dev/sd[abcde]
/dev/sda:
 drive state is:  standby
/dev/sdb:
 drive state is:  standby
/dev/sdc:
 drive state is:  standby
/dev/sdd:
 drive state is:  standby
/dev/sde:
 drive state is:  active/idle

And after i woke them up via reading some data over network:

Code

root@SJOMV:~# hdparm -C /dev/sd[abcde]
/dev/sda:
 drive state is:  active/idle
/dev/sdb:
 drive state is:  active/idle
/dev/sdc:
 drive state is:  active/idle
/dev/sdd:
 drive state is:  active/idle
/dev/sde:
 drive state is:  active/idle

Thanks a lot, I open a feature request to add this info ( stanby, active) in the rigth of the column Temp so in the same webGUI you can easy check both parameters, temp and status.

Quite old but for me still an actual concern...

do you know if such a feature will be added? I would like it, because i see some issue with my disks not always getting into standy, so I would like to have a better overview on them

I don't think because this info is not really important and collecting the information is very expensive (because of calling an external command) and will significant increase the time to process every disk.

You can run a script using a scheduled job that is writing the status to a text file.

Thanks at least for the feedback. I wrote me a small script performing hdparm -C /dev/sd[abcde] with a sleep in a while-loop. This is working fine for me at the moment.

And this leaded me to a point I did not understand:

just opening this page in the webgui in fact I just switched from "disks" to this "smart" spinned up all my disks.

So just opening the page seems to activate all HDD, perhaps by making some hard-dis scan. It is reproducable, e.g. just waiting until disks are in standby and switching to a different menu item and back to this page wakes up the disks.

is it normal and intended? I suppose no?
