[PATCH 00/10] mdadm tool: add the support for cluster-md

[gqjiang@suse.com]

From: Guoqing Jiang <gqjiang@suse.com>

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".

Guoqing Jiang (10):
  Add nodes option while creating md
  home-cluster while creating an array
  Create n bitmaps for clustered mode
  Show all bitmaps while examining bitmap
  Add a new clustered disk
  Convert a bitmap=none device to clustered
  Skip clustered devices in incremental
  mdadm: add the ability to change cluster name
  mdadm: change the num of cluster node
  Reuse the write_bitmap for update uuid
