RAID 5+Spare and RAID 6+Spare

A RAID+Spare volume gives you a “hot-spare” that is ready to synchronize data immediately should a hard

drive fail. If a hard drive in the volume fails, the data starts to synchronize with the spare. The clear advantage

for a RAID volume with a spare is that you do not have to wait for a replacement hard drive. However, the spare

cannot be used as storage during standard operation since its sole task is to take over should a hard drive fail.

You can replace the failed hard drive immediately and, once synchronization is complete, assign it as new hot

spare.

Important info: For RAID+Spare volumes, data remains intact when a single hard drive fails and the spare

begins synchronizing automatically. However, if a second hard drive in a RAID 5 volume fails before

synchronization is complete, all data in the volume will be lost. The same is true for a RAID 1 volume. In the

case of RAID 10, the second failed hard drive would have to be on the same mirrored set as the spare hard

drive.. RAID 6 allows for two hard drives to fail.
