==== Receive periodic check of Raid by mail ====
 +
 +
There are routines in SME Server to check the raid and sent mail to the admin user, when the raid is degraded or when the raid is resynchronizing. But the admin user receive a lot of mails and some time messages can be forgotten.
 +
So the purpose is to have a routine which sent mail to the user of your choice each week.

# cron.weekly/mdadm-status -- weekly status of the RAID

# Get status from the RAID array and send the details by email.
 +
# Email will go to the address specified in the commandline.
