I have an Intel software RAID 0 setup with two 500GB disks (i.e. "fakeraid"). The metadata on one of the disks has been lost and so the array will no longer activate.
I know the order of the disks, the stripe size, and the total size of the RAID set. Using this information, is there any way to force either dmraid, mdadm or something else to activate the array so that I can (hopefully) back up as much data as possible before the faulty disk completely dies?
I should probably point out that the RAID volume was partitioned using GPT rather than MBR, so it should be possible to restore the partition table from the backup even if it gets nuked in the process of re-activating the array.
