A city database PVC uses access mode ReadWriteOnce. Two application Pods on different nodes both try to mount it read-write. What should the admin expect?
Select an answer to reveal the explanation.
Short Explanation
RWO is a single-workshop rule: one node gets the writable mount. Two Pods on different nodes fighting for the same disk usually lose—the volume won’t attach everywhere like a shared network share. If you need many nodes writing, that’s RWX territory (and a backend that supports it).
Full Explanation
Access mode ReadWriteOnce (RWO) means the volume can be mounted as read-write by a single node. Multiple Pods on that same node may share the mount, but Pods on different nodes generally cannot both mount RWO read-write. It does not auto-upgrade to RWX, and it is unrelated to Ingress.
