I am building a new (power) system. MOBO is a ASUS Sabertooth 990FX. I've installed:
- 1 500GB HD for the OS and user accounts (mounted at /)
- Three 2TB drive set up on the BIOS as a single raid0 (mounted at /raid)
The issues is that I cannot confirm the size of the raid from the mount point. When I look at the properties of /raid it tells me "free space: unknown". I am unsure of the output I'm getting from fdisk -l as this is my first foray into raid.
fdisk is inconclusive and "cat /proc/meminfo" appears to indicate that I'm not getting the memory I expect (see below!).
Any assistance will be greatly appreciated.
