removing a first identification of the first node from the respective identifications in the listing based on the reply from the first node, wherein the reply indicates that a checkpoint function associated with a shared lock of the respective shared locks has completed at the first node,
wherein the operations further comprise, prior to the receiving the reply, starting a counter associated with the first checkpoint call, wherein the counter identifies a quantity of nodes in the group of nodes, and wherein the removing the first identification of the first node comprises decreasing the quantity of nodes by one digit.
