Fellow gurus,
I've just recently made the switch over to an Areca card (specifically the ARC-1230). I have an expansion question specific to how Areca works their volume structuring.
Example (over-simplifying for clarity - this is not my setup):
- 'Raid set' of 3x 500gb drives, 1500gb raw capacity.
- 'Volume set' - 1tb raid-5 created within the above raid set.
With the above example, what precisely happens if the user wants to expand capacity, not by adding drives to the array, but by replacing drives with those of a larger capacity? Is it possible to intentionally fail the array by replacing a 500gb drive with a 1tb drive, allowing a rebuild, then repeating for the other 2 drives? If this is done (and is allowed / works), does the raid set raw capacity simply jump to 3000gb allowing later expansion of the volume set to 2tb, or is there some hidden step I am missing?
As a side question, I know with other controllers' interfaces you could have 2 1tb drives and 1 500gb drive, and you could make a raid-5 taking the first 500gb of all 3 and a raid-1 using the 2nd half of the 2 1tb drives. Is this possible with the way Areca does their raid sets?
Thanks in advance for your assistance
