V3 changes: 1. re-orgnize some codes to ensure mdadm compiles after each patch is applied 2. change the code for super1.c for first patch since it has side effect for non-cluster condition V2 changes: 1. re-arrange the squence of patches 2. add some memembers into sb_le_to_cpu 3. handle some logic change and comments from Neil Basic background for Cluster MD: Cluster MD is a shared-device RAID for a cluster, currently, the implementation is limited to RAID1 but with further work (and some positive feedback), it could be extend to other RAID levels. The kernel part code of cluster-md has been sent to maillist several month ago by Goldywyn, and to make cluster-md works, the mdadm tools also need to do some changes accordingly. This patch set extends mdadm tool to aware cluster MD scenario, and handle related cluster-md scenario. 1. the first part (0001-0007) comes from Goldwyn, which add initial support for cluster-md, those changes included make mdadm awares nodes, home-cluster and n bitmaps for clustered mode, also let mdadm can confirm disk which is added by another node. 2. the second part is for support change cluster-name and node nums under assemble mode. Which extend write-bitmap to handle above cases, and also use the extended write_bitmap for update uuid. [PATCH V2 10/10] is just compiled test only. BTW: this series is based on commit "72a457 IMSM: Count arrays per orom".
