I want to use a CSI volume in multiple jobs and got
Constraint 'CSI volume xxx has exhausted its available writer claims' filtered 8 nodes
I thought when I register a volume with multiple-node-multiple-writer a volume can be used from different nodes and therefore jobs. But obviously this is not so.
As far as I know, you have to make sure your plugin supports multiple-node-multiple-writer, for instance, aws ebs doesn’t support that.
For further reading, you can look here for the specification for each volume driver, refer to the ‘Supported Access Modes’ column.
