Re: checkarray not running or emailing

[Ram Ramesh <rramesh2400@gmail.com>]

This may be a silly question, but is email working in your system?

I run debian, but a different version. Cron only sends me a message when 
something is wrong. I mean if checkarray failed, I get a message. If my 
array is degraded, I get a message. If everything is fine, no message. 
May be that is the standard. I am not the authority, but that is what is 
happening in my system.

I believe cron emails stdout+stderr of the command run. May be 
checkarray does not output anything in a successful run and therefore no 
email.

It is best to also query debian.user email: debian-user@lists.debian.org
