---------------------------------------
Summary: Increase available space requirement during
pipeline/container allocation
Key: HDDS-13922
URL: https://issues.apache.org/jira/browse/HDDS-13922
Project: Apache Ozone
Issue Type: Sub-task
Components: SCM
Reporter: Siddhant Sangwan
Currently we use "ozone.scm.container.size" (5GB default) in various
implementations of PipelineProvider and in
ContainerManagerImpl#getMatchingContainer when checking if a DN has enough disk
space for a container.
The problem is that if only 6 GB is remaining, this check will return true
concurrently for multiple clients. But there's only space for 1 container,
leading to container creation failures for all but 1 client. So we should
increase this space requirement to a multiple of container size.
