Csi volumes not shareable across jobs on the same node?

My understanding was that for example the csi mounts with “single-node-writer”
would only be write mountable to one node but jobs on the same node should be able to use that mount.

Seems like that’s not the case though as I’m getting the following error when deploying a second job with the same csi mount

Constraint CSI volume vol1 has exhausted its available writer claims filtered 1 node

I doubt that.

SINGLE_NODE_WRITER can only be published once as read/write on a single node. It can’t be published to more than one node and it can’t have more than one task attached to it.
