I need to know how can I get email alert if one of raid 1 disks fail to work/crashes. I have CentOS 6.4 64bits, software raid.
I did some mistake folowing this tutorial, because it was a bottom note
NOTE: It has been found that mdadm will not send an e-mail if the DEVICE partitions section does not exist in the /etc/mdadm.conf file. If those sections do not exist a new /etc/mdadm.conf file can be created by using the following command: mdadm –detail –scan > /etc/mdadm.conf"
I executed that line and my mdadm.conf file was empty whith that response from ssh :
"mdadm: An option must be given to set the mode before a second device (–scan) is listed"
I also undestand I have to start it using this ssh line:
mdadm –monitor –scan –daemonize
but I get this response
mdadm: An option must be given to set the mode before a second device
(–scan) is listed
this is 'cat /proc/mdstat' :

mdadm.conf file generated 1 minute ago with mdadm --examine --scan > /etc/mdadm.conf :

Is this enough to get email notifications if one hdd fails for my case ?
