LCOD 11.14.07 – Quick RAID check script for cron

Posted by Jon Zobrist in Bash, Linux, Linux Command of the Day, Programming on November 14, 2007

This is a quick script that will let you run the new raid checks, or repair, or pause a running raid check. It doesn’t do e-mails or anything, and from what I read on this thread it’s something mdadm needs to be set to watch for. I ran the check on a RAID and received no output, so I guess it was ok?

I will update the script as I find out more. I’d like to add a simple escalation from check to rebuild? (I think it does this anyways), and an e-mail status report, or even a syslog call saying I ran all things look good.
