Problems with N40L 4x2TB RAID0 in Ubuntu

[bohmwu 0]

Just purchased the N40L from buy, received well, first tried win7, nice and decent,

however, I need many php and java service, therefore the best way is using linux, or in other words, ubuntu, which is my best choice, I am not expert, and very lack of knowledge.

 

ubuntu was successfully installed on the 250GB hard drive, i had 4 x 2tb, and I set them up as RAID0. in the win7, it worked as it should be, and i used GPT for them.

but in the ubuntu, it was been told there is a Raid, and need be activated, i chose yes, and it shows only 1.4tb (with something mapped-h.....), which should be 8tb or at lease 7.2tb in windows.

 

when the installation was done, I couldn't find the location for the series of raid. or because my little knowledge for linux? /dev/sde or else isn't available

 

tried fdisk to check.. like below

then I installed gparted

 

 

anyway, My target is (very simple):

1. keep ubuntu (version at least 9)

2. use hardware raid0 for 4 hard drive

SINCERELY THANKS INDEED!!!!

Not knowing anything about ubuntu what I'd try is re-installing win7, delete the RAID 0 partion (7.2TBish), blow away Win7, re-install Ubuntu and see if it picks up the 4x2TB disks properly. If you already worked this one out I'd love to know how you did it.
