Guoqing Jiang 7564beda19 md-cluster/raid10: support add disk under grow mode ... For clustered raid10 scenario, we need to let all the nodes know about that a new disk is added to the array, and the reshape caused by add new member just need to be happened in one node, but other nodes should know about the change. Since reshape means read data from somewhere (which is already used by array) and write data to unused region. Obviously, it is awful if one node is reading data from address while another node is writing to the same address. Considering we have implemented suspend writes in the resyncing area, so we can just broadcast the reading address to other nodes to avoid the trouble. For master node, it would call reshape_request then update sb during the reshape period. To avoid above trouble, we call resync_info_update to send RESYNC message in reshape_request. Then from slave node's view, it receives two type messages: 1. RESYNCING message Slave node add the address (where master node reading data from) to suspend list. 2. METADATA_UPDATED message Once slave nodes know the reshaping is started in master node, it is time to update reshape position and call start_reshape to follow master node's step. After reshape is done, only reshape position is need to be updated, so the majority task of reshaping is happened on the master node.
