RAID mdadm - Sending E-Mails on RAID Failure?

rootking · 12-24-2007, 10:36 AM

I've seen how you must add the MAILADDR line to your /etc/mdadm.conf file to tell mdadm that you want to send an email to this address when your RAID is degraded. The problem is that I need to know the easiest way to send out that e-mail w/o configuring a mail server on this machine.

Is there a quick way of sending an e-mail when mdadm detects a degraded array?

thanks for any help

Then you'll need to write a script. Perhaps something that:

1. Checks the container and when it sees a failed drive, touch a file.
2. Put that script into cron and have it run every 10 mins or so
3. Have a different machine with sendmail or whatever MTA you have and ssh into the machine and check if the file exists
4. If it does, then fire the mail.
