diskFillFraction does not work

[JimStorage]

in file: cmd/global.go , "diskFillFraction = 0.99" is upper limit of the fraction of a disk allow to be filled
but In my real environment, disk space is used up.
Who could told the reason, I will be appreciated.

@JimStorage This is only enforced in erasure coded mode. Without more info that is my guess.

I think it's running in erasure coded mode.

@JimStorage The fill-disk fraction is not a sleeping pillow. You should monitor your disk use.

MinIO uses storage for transient data, so you can easily get beyond 99%.
