This procedure describes how to remove a seed node from the seed list.
Verify that the seed node you want to remove is listed as a seed node in the
scylla.yaml file by running
cat /etc/scylla/scylla.yaml | grep seeds:
Update the Scylla configuration file, scylla.yaml, which can be found under
/etc/scylla/. For example:
Seed list before removing the node:
- seeds: "10.240.0.83,10.240.0.93,10.240.0.103"
Seed list after removing the node:
- seeds: "10.240.0.83,10.240.0.93"
Scylla will read the updated seed list the next time it starts. You can force Scylla to read the list immediately by restarting Scylla as follows:
sudo systemctl restart scylla-server
sudo service scylla-server restart
docker exec -it some-scylla supervisorctl restart scylla
(without restarting some-scylla container)
