Description

Add guardrails for disk usage establishing soft/hard limits on the percentage of used disk space. For example:

# Warning threshold to warn when local disk usage exceeds threshold. Valid values: (1, 100]
# Defaults to -1 to disable.
# disk_usage_percentage_warn_threshold: -1

# Failure threshold to reject write requests if replica disk usage exceeds threshold. Valid values: (1, 100]
# Defaults to -1 to disable.
# disk_usage_percentage_failure_threshold: -1
