Description Neha Ojha 2019-01-19 02:41:15 UTC 
Description of problem:

We overestimate the size of the object for reads with trimtrunc, which results in the hitting assert((offset + length) <= (range.first.get_off() + range.first.get_len())) during reads.



Actual results:

The above failure seen in the multimds suite with EC pools.


Expected results:

No failure during EC pool reads.
