📄️ Hot Spare

A hot spare disk is a backup hard disk. When a hard disk in the storage pool fails, it can quickly and automatically take over to ensure the continuous and stable operation of the storage pool. To ensure performance and compatibility, it is recommended to choose a hot spare disk with the same model as the existing hard disks in the storage pool. The capacity of the hot spare disk should be at least equal to the smallest member disk in the storage pool; however, if your storage pool uses the TRAID or TRAID+ array type, the capacity of the hot spare disk should be at least equal to the largest member disk in the storage pool.
