minfreespace limits
Key: HDDS-14925
URL: https://issues.apache.org/jira/browse/HDDS-14925
Project: Apache Ozone

Proposing to use 25%(of hard limit) as soft limit. Current hard limit is 2%
Example: 16TB disk, Current hard limit min free: 320GB
Proposal:
|<----------320GB (2% of total disk space)--hardlimit--->| *Current*
|<--{*}80GB (0.25%){*}--soft ->|<------240GB--hardlimit---->| *Proposed*
DN will report soft + hard limit(320GB) to SCM, and DN while allocating a new
container or during write chunk it should allow up to hard limit.
