Turned out, smartd kept saying, that it had no entries in smartd.conf.

I've copied smartd.rpmnew over smartd.conf, restarted it,
now I have (in /var/log/messages, date+hostname removed):

smartd version 5.38 [x86_64-redhat-linux-gnu] Copyright (C) 2002-8 Bruce Allen
Home page is http://smartmontools.sourceforge.net/
Opened configuration file /etc/smartd.conf
Configuration file /etc/smartd.conf was parsed, found DEVICESCAN,
scanning devices

Device /dev/sda: using '-d sat' for ATA disk behind SAT layer.

Monitoring 0 ATA and 2 SCSI devices
smartd has fork()ed into background mode. New PID=3427.

And the /etc/smartd.conf contains:
DEVICESCAN -H -m root
and the rest are comments.

Do you think it is configured okay this way?

My disk info is:
