advice with erasure coding

[Maged Mokhtar <mmokhtar@xxxxxxxxxxx>]

Good day Cephers,

I want to get some guidance on erasure coding, the docs do state the different plugins and settings but to really understand them all and their use cases is not easy:

-Are the majority of implementations using jerasure and just configuring k and m ?
-For jerasure: when/if would i need to change stripe_unit/osd_pool_erasure_code_stripe_unit/packetsize/algorithm ? The main usage is rbd with 4M object size, the workload is virtualization with average block size of 64k.

Any help based on people's actual experience will be greatly appreciated..
