H. Peter Anvin announced on the linux-raid mailing list this morning that he has finally had some success in his attempt to implement software RAID-6 on Linux.


RAID-6, like RAID-5, is a parity RAID, but instead of using a single disk for parity informaiton, it uses two disks (two-dimensional parity). This results in the ability to survive two disk failures without a replacement or rebuild.


His code is still extremely experimental, but you can download and help test if you so desire:
