For one of my pools I have 107TiB STORED and 298TiB USED. This is strange, since I've configured erasure coding (6 data chunks, 3 coding chunks). So, in an ideal world this should result in approx. 160.5TiB USED.
There are 473+M objects stored. Lot's of these files are pretty small. (Read 150kb files). Not all of them though.
I suspect that the stripe size is related with this issue. This is still the default (4MB), but I am not sure.
I seem to recall something about EC not "working" as expected when your files/objects are smaller than some predefined size, in which case it will not make the 6+3 split for you. It would be silly to have a 6-byte object split into 1-byte parts, so in such cases I think it becomes repl=6 or repl=9 (for 6+3 profiles) or something which could explain your experience. -- May the most significant bit of your life be positive.
