Wait ..... Was this is a repeat of a problem reported earlier ??????

Do you have your data backed off where you can play????

I think that happen since the array was built with 250 gig. The array was bassed on it. The size is bassed on the smallest drive.

Did you upgrade to v4.1 like you mentioned earlier????

Set to JBOD (4 x 500) then back to Raid 5.
Check to see if it reconize the drives as 480 gig.

Then I would do a re-format of the drives, making sure no hidden markers from breaking the raid to jbod.

The set the raid 5 array up.

I think this is a repeat of what happen earlier.........

Looks like this is going to be a learning exercise for us. New to Guardian OS.
What works with Snap OS does not seam to apply to the Guardian OS.
