Raid

=Raid= An Inveneo server has 2 hard drives, which are raided to help protect data from hard drive failure. IHL uses raid 1, which takes all of the data from one drive and copies it to the other drive. The drives are mirror images of each other. If one hard drive fails, the other hard drive will continue to work, allowing the server to run and backup copy of user files. =Raid Status=

Checking the Status
Inveneo Hub Linux supports RAID 1. By default, the server is configured for software RAID. The homepage for the webmin shows the status of the RAID array. (To log into the webmin, see Chapter 1: Accessing the Webmin.) A normal, healthy array will show 2 hard drives, each with 3 partitions. Both hard drives will be green. 

Raid Failure
When a hard drive fails, IHL will play of series of beeps once every hour. If IHL is connected to the Internet, IHL will send an email stating that a hard drive is failed. To configure the email notification, see Raid Notification Management. The webmin will also show a failure of a hard drive of Drive 2. 

Raid Rebuilding
When a hard drive fails, it should be replaced with a new a drive. For instructions on replacing a hard drive, see the Inveneo Hub Server Hardware Manual; Chapter 5: Replacing Hard Drives. Once the server is turned on with the new hard drive, IHL will automatically begin rebuilding the Raid array by coping data from the working hard drive to the new hard drive. The status of the Raid rebuild can be seen in the webmin. 

=Raid Notification Management= When IHL is connected to the Internet, it will send an email saying that a hard drive has failed on the server. By default, it will send an email to Inveneo. However, it can be configured to send an email to someone else. To change where it sends emails, go to Inveneo Raid Notification Management module under System in the webmin.
