V4 changes: 1. update documation for syntax correct and add missed infos 2. code modification for remove duplicated code and coding style etc 3. make cluster name only appear in bitmap 4. add UUIDUpdate handling to write_bitmap0 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.
