Introduction to the high watermark of OceanStor 9000 V100R001C01
In OceanStor 9000 V100R001C01, the default high watermark is that the used space occupies 85% of the total storage space of a node pool. When the used space of a node pool reaches the high watermark, the system reports a capacity insufficiency alarm, and refuses data to be written to the node pool. By default, the alarm clearance threshold is 5% lower than the high watermark. That is, when the percentage of used space is lower than 80%, the capacity insufficiency alarm is cleared. The alarm threshold and clearance threshold of the high watermark can be manually changed.

Method used to recover data on OceanStor 9000 V100R001C01
Based on failed objects and data recovery triggering conditions, OceanStor 9000 V100R001C01 recovers data using two methods: ensuring zero data loss on the original disk or node and writing the data in a failed disk or node to other normal disks or nodes through calculations.
