Linux Raid

This site is intended as a reference for Linux software raid as implemented in the latest kernel.

Where possible, information should be tagged with the minimum kernel/software version required to use the feature.

Linux raid issues are discussed in the linux-raid mailing list to be found at http://vger.kernel.org/vger-lists.html#linux-raid
