RAID Manager
The Software RAID app provides status information, reporting and interaction for administering a software RAID array. This app is a UI integration and interface for the ubiquitous madadm software RAID management tool.
Installation
If your system does not have this app available, you can install it via the Marketplace.
Menu
You can find this feature in the menu system at the following location:
Configuration
The configuration of the app is very simple. Monitor array and if so, how often.
Level
Displays the software RAID array level detected (eg. RAID-0, RAID-1, RAID-5 etc.)
Monitor RAID
If enabled, the app will automatically create a summary of the RAID array for the purposes of emailing out a report.
Frequency
Determines how often to run the report. If a large array is rebuilding (syncing), you may want to disable notifications or decrease the frequency so you are not being bombarded with emails.
Send Email Notification
There are two possible settings:
On Failure
On failure means an email alert will only be sent in the event an array's status changes from 'Clean' to 'Degraded'. If an array continues to stay in the degraded state (eg. the state does not change), only one email will be sent when the event occurred, regardless of the 'frequency' setting.
Future email alerts will not be sent during the repair/rsync of the array, since the warning level is set only to alert “On Failure”.
Always
Setting to “Always”, means you will receive an alert any time the status of your RAID array's change…either for good or worse. If you have selected a low frequency check time (eg. 1 minute), you will receive emails once a minute during times when the array status is changing (eg. a rsync process).
Set the email address to send notifications to.

Command Line Utility
A command line script is provided for convenience. As root, run:
/usr/sbin/raid-notification
Use the -f flag if you want to force current display of the RAID array and send out an email alert (if notification is enabled).
