RAID Arrays - Can You Only Migrate to Larger Capacities?
I made the mistake of using one too many drives and my current RAID 5 array consists of 9 drives. (16TB)
I'm hoping to migrate this to 8 drives yielding a 14TB RAID5 array. A Sans Digital support engineer told me today that you can only migrate to same capacity or larger.
If the data is only filling half the present array, why is it not possible to migrate from 9 t 8 drives?
Any references to "10 Rules of RAID" or something covering this concern would be greatly appreciated.
