DRBD auto-promotes a resource to Primary during the provisioning path (e.g. mkfs.ext4 against a freshly created replica), but auto-demote sometimes fails to fire on close. The resource then stays Primary on a node that has no consumer, and CSI on the legitimate target node fails NodePublishVolume with "failed to set source device readwrite". The only recovery is an explicit drbdadm secondary on the stuck node. Add a per-satellite plunger handler that detects local Primaries where every device has open == false and demotes them. Both the detection and the action are local to the satellite, so no peer coordination is needed. open:no makes drbdadm secondary safe; if a real consumer is about to arrive, auto-promote will redo it.
