Releasing Nodes from Cluster
----------------------------

To release a node means to remove it from the cluster (e.g., for maintenance). As the node may be running services needed by the cluster, do the following prior to releasing it to avoid cluster degradation:

#. If the node runs one of the five required metadata services, add a metadata role to another node. You need to make sure that the cluster has at least five metadata services running at any time.

#. If the node has any access points, make sure that the same access points are configured on other nodes in the cluster as well.

#. If the node has iSCSI targets, move them to a different node.

#. If the node has an S3 gateway, reconfigure DNS for the S3 access point to remove the node from DNS records. Next, release the node from S3 in the corresponded sections of the **SERVICES** screen.

#. Make sure the cluster has enough storage space to accommodate the data from the released node.
