Disk activity and standby

[JohnnyFive]

Is there any way (CLI is fine) to check why my drives are not going into standby? every few seconds I see the lights on the drives blink, so something is accessing it, and I haven't got a clue what.

[edit]Nevermind[/edit] already found the (linux)command and seen a few reasons.

Hi Johnny,

The system will check the disk temperature and SMART info, which will caused the lights blink but not wake up disks.
Please make sure your NAS have the updated firmware (now is V1.0.6 R1G4) and use below command to check disk status:
hdparm –C /dev/sdx
(sdx is the disk ID)

If there is any problem, please let me know.

I have the same issue seemingly (on latest sw of course) - the led's are blinking every 5-6s but I think they are spinning (I can hear something but it might be the fan or something else).

Is there a way to tell if they are running - ideally from the GUI - e.g. put them into their own category in the system info logs tab - say a "disk log" pulldown - perhaps general hibernation stuff in there too.

Or from the SSH prompt (though the login might wake things up) - perhaps from the system logs of past sleep events in /var/log/messages

I've disabled all the services except for CIFS (and I'm not accessing it) FTP and RSYNCH (and theres no backup jobs) and things like boxee/download server/plex etc.

edit: just noticed the command from above (but perhaps the SSH woke it up ?) :-

# hdparm -C /dev/sda

/dev/sda:
drive state is: active/idle
# hdparm -C /dev/sdb

/dev/sdb:
drive state is: active/idle
# hdparm -C /dev/sdc

/dev/sdc:
drive state is: active/idle
# hdparm -C /dev/sdd

/dev/sdd:
drive state is: active/idle
# hdparm -C /dev/sde

/dev/sde:
drive state is: active/idle
# hdparm -C /dev/sdf

/dev/sdf:
drive state is: active/idle
# hdparm -C /dev/sdg

/dev/sdg:
drive state is: active/idle
# hdparm -C /dev/sdh

/dev/sdh:
drive state is: active/idle
