503 when trying to upload with EC storage policy

[fvennetier]

Hello. For ECLIBEC63D1 you need 9 rawx services. The internal load balancer won't accept to send 2 chunks on the same service. Look for "no service polled from" in the logs of oioswift-proxy-server, oio-proxy or oio-meta2-server to confirm.

This can indeed be found in my /var/log/oio/sds/OPENIO/oioproxy-0/oioproxy-0.log file:

warning  1341 42D4 log WRN oio.core no service polled from [rawx], 3/9 services polled

In retrospect, the warning makes sense, however it could definitely be more clear ("Request for 9 services from pool [rawx] could not be fulfilled because only 3 services currently exist in that pool"). In addition to the warning, I would hope that at least one of the services would log an error. It does make sense that this particular one is a warning (client asks for impossible thing != server malfunction). However, by comparison, when I had configured a non-existent storage policy, I did get an explicit error logged from one of the services (I don't remember which).
