I'm not sure to understand what is displayed in stor2rrd regarding pool capacity.
From Hitachi Command Suite : Yesterday
From Hitachi Command Suite : Today (8TB more in Used Capacity)
The Capacity in HCS seems to be = Used + Free in stor2rrd.
However both values in stor2rrd seem wrong : Used max is 114.03TB while the actual Used in HCS is 128.75TB
Moreover, the "blank period" of the stor2rrd graph seems to be taken into account for the average calculation.
The 4 weeks graph is also strange, it doesn't show any increase while during the 24h the used capacity increased by 8TB at least (seen in HCS).
Am I missing something ?
