can you show some details about "volume conflicts"?
In our cases for NodeGroup upgrade, we often do it with the following steps:
- create NodeGroups with the new version
- cordon nodes in the old NodeGroups
- trigger a rolling restart (e.g by adding an annotation)
- wait until all pods moved into the new NodeGroups
- delete old NodeGroups

Hi @csuzhangxc, thanks for the response.
Should they happen again, I'll collect and share the errors related the volume conflicts.
It sounds like you are describing this doc: Replace Nodes for a TiDB Cluster on Cloud Disks.
Which we previously had not done and probably the reason for the pod errors. I'll close this issue.

Yes. The steps are just as Replace Nodes for a TiDB Cluster on Cloud Disks.
