[systemd-devel] systemd and smartd daemon

[Al Lau]

Hi,

I am seeking help and advise on troubleshooting the starting of the smartd
daemon.  The /usr/sbin/smartd comes from the smartmontools version 6.3.

The /usr/lib/systemd/system/smartd.service file looks like this

# cat /usr/lib/systemd/system/smartd.service
[Unit]
Description=Self Monitoring and Reporting Technology (SMART) Daemon
Documentation=man:smartd(8) man:smartd.conf(5)
After=syslog.target

[Service]
Type=forking
PIDFile=/run/smartd.pid
ExecStartPre=/bin/rm -f /run/smartd.pid
EnvironmentFile=/etc/sysconfig/smartmontools
ExecStart=/usr/sbin/smartd $smartd_opts
ExecReload=/bin/kill -HUP $MAINPID
StandardOutput=syslog

[Install]
WantedBy=multi-user.target

When "systemctl start smartd.service" is called, the process forks into a
daemon.  The problem I'm seeing is that the forked process received a
SIGTERM signal and exited.  How do I resolve this so that the forked
process would not get terminated.

# systemctl status smartd.service
smartd.service - Self Monitoring and Reporting Technology (SMART) Daemon
   Loaded: loaded (/usr/lib/systemd/system/smartd.service; enabled)

Apr 02 17:19:49 007 systemd[1]: Unit smartd.service entered failed state.

To verify, I take the "/usr/sbin/smartd $smartd_opts" and run it from the
command line.  The smartd daemon forks and the daemon process stays up as
expected.

Thanks,
