Issues with Hardware RAID10 on Mint KDE 14

Postby Jguy1987 on Sun Feb 03, 2013 9:17 pm

Hello,

I'm having a bit of trouble and hope there is someone with the knowledge to help me out with this one. I'm running Linux Mint 14 KDE.

I have an Intel Hardware RAID10 setup across (4) 1.5TB WD Green drives. My Linux Mint is installed on a 60GB SSD, so I don't need to boot from the RAID, but I do need to access it from both my Mint install and Windows for gaming and file management.

I've install mdadm but it does not seem to detect that it is a RAID 10, but instead detects a RAID 0 AND a RAID1 as seperate devices.

Outputs from terminal:

vivi ~ # sudo dmraid -ay
RAID set "isw_biefbjcgfc_Raid 10-0" already active
RAID set "isw_biefbjcgfc_Raid 10-1" already active
RAID set "isw_biefbjcgfc_Raid 10" was not activated
vivi ~ # fdisk -l

The KDE Partition manager just lists (4) seperate 1.5TB drives with no partition information on them. I've tried some various instructions but have not been able to figure out why the OS thinks of the RAID as seperate RAID 0 and a RAID 1, instead of a RAID 10.

Any help would be appreciated or...without this working my Linux Mint install will be confined to a virtual machine running on my Windows 7 OS, and I don't want that.

Thanks again for any help you can provide.
