Abstract
A computer data storage system is described. A processor maintains a striped volume set by striping a data container over a plurality of storage nodes. A storage node determines whether space available on that node is below a predetermined threshold, the predetermined threshold indicating a low-in-space state. The storage node sends a message indicating that the storage node is in a low-in-space state. The processor accepts no further write messages to the data container as long as the storage node is in a low-in-space state.
