RADOS import/export? Will look into that. I ended up going with Paul's suggestion, and created a separate zone under the main zonegroup with another RGW instance running that zone, and had it sync the data into the Erasure-Coded zone. Made it very easy to do!
Thanks,
Mac

rados cppool AFAIK lack of support of copy from replicated to EC. May be
now is wrong.
Also you can use rados import/export.
