Introduction to the read-only watermark of OceanStor 9000 V100R001C20 and V100R001C30
In OceanStor 9000 V100R001C20 and V100R001C30, the default read-only watermark is that the used space occupies 90% of the total storage space of a node pool. When the used capacity of a node pool reaches the read-only watermark, the system reports a read-only alarm, and refuses data to be written to the node pool. By default, the read-only alarm clearance threshold is 5% lower than the read-only watermark. That is, when the percentage of used space is lower than 85%, the read-only alarm is cleared and data can be written to the node pool. The alarm threshold and clearance threshold of the read-only watermark can be manually changed.
