Replacing a dead seed node¶
In Scylla, it is not possible to bootstrap a seed node. The following steps describe how to replace a dead seed node.
Verify that the node is a seed node. Use the command below.
cat /etc/scylla/scylla.yaml | grep seeds:
If the dead node’s IP address is in the seeds list, it needs to be replaced.
Perform steps 1-3 for all the nodes in the cluster:
Promote an existing node from the cluster to be a seed node by adding the node IP to the seed list in the
scylla.yamlfile. It can be found under
Remove the dead node IP from the seeds providers list
Restart the node in the cluster using
Replace the dead node using the Replace a dead node procedure
It is recommended to have more than one seed node in your cluster (it’s not allowed to define all the nodes in the cluster as a seed node).
