gadmin cluster expandcommand like below. If the expansion involves changing the replication factor, use the
--haoption to indicate the new replication factor:
node_ip_listis the machine aliases of the nodes you are adding to the cluster mapped to their IP addresses with a colon(
:), and separated by a comma. Below is an example:
m<serial>, such as
m3for a 3-node cluster. If you are adding a fourth node, then the fourth node would be named
m4. If you decide to name them differently, make sure that all names are unique within the cluster.
(1 + Math.ceil(oldPartition/newPartition) ) * dataRootSize.
newPartitioneach stand for the partitioning factor of the cluster before and after expansion;
dataRootSizestands for the size of the data root folder on the node.
(1 + Math.ceil(3/5)) * 50) = 100 GBof free space on the staging path.
