I am playing around with erasure coded pools on 0.78-348 (firefly) and am
attempting to enable EC on the .rgw.buckets pool for radosgw
(fresh install).
If I use a plain EC profile (no settings changed), uploads of various
sizes work fine and EC seems to be working based on how much space is
being used in the cluster. If I start playing with k or m values,
multipart uploads start failing (on the first chunk). I haven't seen
issues with rados put or rados bench on EC pools. I saw the same behavior
on the official v0.78 release.
I turned up verbose logging on OSDs and RGW and I don't see obvious
errors. Here is a snippet from the RGW log from the context/thread
that failed:
