Caution
You're viewing documentation for a previous version of ScyllaDB Enterprise. Switch to the latest stable version.
Failed to create materialized view after node was removed from the cluster.
Error message:
InvalidRequest: Error from server: code=2200 [Invalid query] message="Can't create materialized views until the whole cluster has been upgraded"
A removed node was not removed properly from the seed node list.
Scylla Open Source 4.3 and later and Scylla Enterprise 2021.1 and later are seedless. See Scylla Seed Nodes for details. This problem may occur in an earlier version of Scylla.
Scylla logs show the error message above.
To verify that the node wasn’t remove properly use the nodetool gossipinfo command
For example:
A three nodes cluster, with one node (54.62.0.101) removed.
nodetool gossipinfo

We can see that node 54.62.0.101 is still part of the cluster and needs to be removed.
Remove the relevant node from the other nodes seed list (under scylla.yaml) and restart the nodes one by one.
For example:
Seed list before remove 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"
Restart Scylla nodes
sudo systemctl restart scylla-server
docker exec -it some-scylla supervisorctl restart scylla
(without restarting some-scylla container)
