Failure to Add, Remove, or Replace a Node
|
|
------------------------------------------------
|
|
|
|
ScyllaDB relies on the Raft consensus algorithm, which requires at least a quorum
|
|
of nodes in a cluster to be available. If some nodes are down and the quorum is
|
|
lost, adding, removing, and replacing a node fails.
|
|
|
|
See :doc:`Handling Node Failures <handling-node-failures>` for information about
|
|
recovery actions depending on the number of nodes and DCs in your cluster. |
