Starting a GaussDB Node

Scenarios

GaussDB allows you to manually start a stopped node.

Precautions

• Only nodes in the Stopped state can be started.
• The following operations cannot be performed when a node is being started: scaling up storage, changing specifications, backing up data, resetting passwords, rebooting an instance, and deleting an instance. When you perform these operations, nodes cannot be started.
• After a node is started, the distribution of primary and standby nodes for the instance may be unbalanced. Contact O&M personnel to determine whether to balance the primary and standby statuses for the instance.
• If the number of stopped nodes in a DN shard exceeds half of the replicas of the shard, a single node may fail to be started.
