How do I create a RAID 50/60 storage pool.
To create a RAID 50/RAID 60, you must create a RAID 5/RAID 6 pool first, and then expand the pool to RAID 50/RAID 60. Please note that the minimum number of disks required to expand the pool depends on the type of its RAID group. For example, the number of disks used for pool expansion for RAID 5 cannot be less than 3 (the minimum number of disks required for RAID 5). Similarly, for RAID 6, the number of disks cannot be less than 4.
Use "Actions" > "Expand Pool" to create a RAID 50/RAID 60 storage pool.
