> @tomscut Sorry for being late. I agree with adding more EC logs, but I
feel that the log information is too detailed, and some variables duplicate
with other variables. Could you please make it more concise and descriptive?
Thanks @tasanuma for your review.
These states are related to each other, and if the upper and lower states
don't match, there is something wrong with the process in between.
Maybe `nonExcess` and `storage2index` are the same. But in some abnormal
cases, we are not sure whether index will be calculated incorrectly,
`storage2index` may cause elements of the same DN with different index to be
overwritten.
If simplify this log, I would remove `nonExcess` and keep the rest. Do you
think this is OK? Thank you.
