The LUN snapshot resource pool uses the internal space of the storage pool. When the space usage of the storage pool reaches the high watermark, an alarm is generated. When the space of the storage pool is used up, the snapshot function is disabled. Hosts can still access LUNs to which space has been allocated. Snapshots of the file system use the space of the file system. When the percentage of space used for storing file system snapshots exceeds the preset percentage, no alarm is generated, and the available capacity of the file system is used. When the used capacity of the file system exceeds the threshold, an alarm is generated.
