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
Problem creating device name scan list
Device: /dev/sda, opened
Device /dev/sda: using '-d sat' for ATA disk behind SAT layer.
Device: /dev/sda, opened
Device: /dev/sda, not found in smartd database.
Device: /dev/sda, is SMART capable. Adding to "monitor" list.
Device: /dev/sdb, opened
Device /dev/sdb: using '-d sat' for ATA disk behind SAT layer.
Device: /dev/sdb, opened
Device: /dev/sdb, not found in smartd database.
Device: /dev/sdb, is SMART capable. Adding to "monitor" list.
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:
# df -h
