Description Marc Schütz 2015-03-06 15:05:02 UTC

My /etc/smartd.conf contains:

DEVICESCAN -d removable -m root,@ALL -M test -M exec /etc/smartd_warning.sh

When I start smartd.service, it tries to send the test email as requested. It calls the warning script with the arguments `-s "SMART error (EmailTest) detected on host: kaim root"`, but the script doesn't accept arguments and aborts.

Comment 1 Stanislav Brabec 2015-03-09 16:12:47 UTC

You are using this feature in an incorrect way.

"-M exec /etc/smartd_warning.sh" means:

    exec  PATH - run the executable PATH instead of the default mail
    command, when smartd needs to send email.  PATH must point to an
    executable binary file or script.

You are not (re)defining warning script, as you intended. You are redefining mailer to something, which is definitely not a mailer.

What happens for you:
smartd calls /etc/smartd_warning.sh to send a test mail

/etc/smartd_warning.sh formats a mail and attempts to send the mail using /etc/smartd_warning.sh as mailer.

Hopefully for you, /etc/smartd_warning.sh does not accept args, so it returns with error. If it would continue, you would get a fork bomb.

All warnings are directed to /etc/smartd_warning.sh, and there is no option to change path of the warning script.

Everything works for me. Just try:

DEVICESCAN -d removable -m root,@ALL -M test


The only thing that can be improved, is a creation of /etc/smartd_warning.d for plugins. I'll do it in the next commit.
