Hello, i am setting Terastation 5800 with 24 TB to RAID1. I followed instructions to delete previous default array (RAID6, 19 TB), but now when i add all available eight drives to build RAID1 array, i only have 2,762 TB of storage amount, which is clearly too small amount for RAID1 configuration. How can i correctly build 12 terabytes of RAID1 space?
RAID1 will only use 2 HDDs, hense the amount of space you are seeing.
