Abstract
A clustered storage system may include potentially many different nodes, each including a storage driver and a kernel module. A node may mount a virtual storage volume for the use of a container application at the node. The storage driver and kernel module may receive a request from a storage driver at a different node and respond by indicating whether the virtual storage volume is in active use. In this way, the clustered storage system may safely but forcibly unmount a virtual storage volume having a failed or hanging mount point so that the volume may be mounted on a different node.
