The storage server issues three different types of out-of-space messages whenever the Extent Pool or Extent Repository space runs short. When a configured warning watermark is reached, the physical space is completeley exhausted, or the capacity constraints have been relieved, a message is received. A log entry for the sysadmin to react to is generated in any case. In case the physical space is completely exhausted, sense data that reads "no space left on device" is received. In this case, currently running I/O will be blocked until space has either been released or added to the extent pool, and a relieve message was received via an attention interrupt.
