From: Guoqing Jiang <gqjiang@xxxxxxxx> 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 10/10] is just compiled test only. BTW: this series is based on commit "72a457 IMSM: Count arrays per orom".
