Bug 674629

smartd does not monitoring hard drives

Description of problem: 

smartd is starting normal, but it does not write SMART data to /var/log/messages. At the same time I can check the disks with smartctl without any problems.

I have standard line in /etc/smartd.conf
DEVICESCAN -H -m root -n standby,10,q

After reboot smartd writes the following lines to /var/log/messages

================================================================

You can see that smatrd detected my hard drives, but smartd will never log any SMART information. For instance, if I issue command "killall -USR1 smartd" then smartd nothing writes to console and put just one line to /var/log/messages

Feb  2 20:18:08 localhost smartd[1452]: Signal USR1 - checking devices now rather than in 1627 seconds.

I have tried to replace DEVICESCAN line by "/dev/sda -a -d sat" with several modification, but result was always the same - no SMART info in /var/log/messages.

Surprisingly smartctl command working fine

Commands "smartctl /dev/sda" and "smartctl /dev/sdb" produce expected output with SMART information. 


Version-Release number of selected component (if applicable):
smartmontools-5.40-3.fc13.i686
I have fully updated F13 (i386) PC. The same behaviour is observed on my F14 machine.

Expected results:
I guess that smartd should write SMART information to /var/log/messages regularly.
