HDD spindown info as normal user (script)

benjalien · 12-02-2013, 07:31 AM

Hi all,

I'm trying to monitor my HDD spin state: are they running or idle.
I have a build a small script using hdparm, but it needs to be run as root, wich is absolutely not an option.

Does someone know how I could get this info a normal user? Some cat /proc/something?

Thanks!

Benjamin

Did you have a look at /sys/block/sd?/device/?

state might be of interest to you.

Thanks a lot, indeed it looks like what I'm looking for

Now I just need to find out what are the different states...

running is one (confirmed) and I do believe offline is another one (cannot confirm that atm).

Well, I think I rejoyed too quickly...

root@raid:/home/benjalien# cat /sys/block/sdf/device/state
running
root@raid:/home/benjalien# hdparm -C /dev/sdf

/dev/sdf:
SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
drive state is: standby

One command is giving "standby" and the other "running" :'(
