Cyclone use du -sh to get memory usage, read the annotation of -h for du command:

-h "Human-readable" output. Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte.

Please pay attention to the unit : Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte. Instead of Kibibyte, Mebibyte, Gibibyte, Tebibyte and Pebibyte.

Unfortunately, we use the following formula to calculate:

var unitMap = map[byte]int64{
	'B': 1,
	'K': 1024,
	'M': 1024 * 1024,
	'G': 1024 * 1024 * 1024,
	'T': 1024 * 1024 * 1024 * 1024,
}

And It is obviously wrong, since 1 Mebibyte=1000Kibibyte (1M=1000K).

There are two ways to fix it:

• correct the formula from 1 Mebibyte=**1024**Kibibyte to 1 Mebibyte=**1000**Kibibyte
• find a way to get PVC usage with Kibibyte, Mebibyte unit.
