It loads a designated erasure-code plugin and calls its
methods. It is convenient to figure out and tune the number of data
chunks, the size of an aligned chunk etc. For instance:
ceph_erasure_code \
--parameter erasure-code-plugin=jerasure \
--parameter erasure-code-directory=.libs \
--parameter erasure-code-technique=reed_sol_van \
--parameter erasure-code-k=2 \
--parameter erasure-code-m=2 \
--all
displays the chunk size when encoding an object of 1024 bytes.
get_chunk_size(1024) 512
get_data_chunk_count 2
get_chunk_count 4
