How to expand storage pool in QES NAS
The procedure of expanding the pool on a NAS running QES system is different from those using QTS system. You can only expand the pool by adding a new RAID group. You cannot expand the pool by adding new disks into existing pool. Please note that the new RAID group will use stripe to expand the storage pool.
To avoid data loss in the event of RAID group failing, please ensure you have a proper backup plan.
