RAIDs The background disk scan is enabled by default. To disable the background disk scan, go to the Storage > RAID Sets screen and click the RAID Settings button. Notes • If the background disk scan is disabled, it will still initiate a scan on a RAID if problems are detected on one of the RAID drives. • The background scan will not run on RAIDs that are degraded, syncing, or rebuilding. RAID Management Tools SnapServers use the following tools for configuring and monitoring RAIDs: Function Ongoing Maintenance Email Notification Navigation Path Navigate to the Storage > RAID Sets screen, from which you can create, assess, edit, and delete RAIDs. You can also disable or enable the Background Disk Scan and the automatic assignment of GuardianOS-partitioned unused disks to a degraded RAID. The server can notify you when a RAID is degraded, failed, or has experienced another error or maintenance condition. This allows you to take action to ensure workflows are not disrupted (Server > Email Notification). You can view the status of your RAID sets on the Storage > RAID Sets and Monitor > System Status screens. RAID Groups Two RAIDs can be grouped together to neatly resolve a number of capacity issues. For example, a volume on one RAID nearing full utilization can be expanded using spare capacity on another RAID. The ability to grow volumes beyond the capacity of a single RAID allows administrators to expand a volume without reconfiguring RAIDs and allows users to continue working as usual with no interruption. Grouped RAIDs must be the same type; you can group two RAID 1s or two RAID 5s (e.g., you cannot group a RAID 1 and a RAID 5). Note Only RAIDS of the same PE (physical extent) size can be grouped. If you are growing the volume on one RAID to use free capacity on another RAID, you will only be allowed to select from those RAIDs that can be grouped. 54 SnapServer Administrator Guide
