RAIDs
54 SnapServer Administrator Guide
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:
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.
Function Navigation Path
Ongoing Maintenance 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.
Email Notification 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).
