You're in the recovery shell ... does/can that use all available ram?
(Like DOS needed special drivers to use ram above 1MB). So I doubt you
need more ram.

Get a rescue disk of some sort, boot into that, so you've got a full
working linux off DVD/CD, and see if you can assemble the arrays from there.
