Hi,
Is there a way to find out if a cluster is near full via librados?
The reason I'm asking is that I'm working on a deployment of the RADOS
Gateway and one of the potential problems I see is that the RADOS
Gateway can keep writing and filling up the whole cluster.
It's obvious that it's the admin's responsibility to make sure that
doesn't happen, but what I'd like to do is make the RADOS Gateway deny
PUT requests when the cluster is near full.
That way normal meta data operations (thus writes) can continue, but new
objects won't be accepted until the cluster has enough space available.
This might also be useful for librbd. Refuse the creation of new RBD
images so that existing images can continue operating.
