Summary: Improve Volume Scanner Health checks
Key: HDDS-8782
URL: https://issues.apache.org/jira/browse/HDDS-8782
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Ethan Rose
Assignee: Ethan Rose
The volume scanner/disk checker currently only checks filesystem permissions
and directory existence. It should also do write, sync, and read back from a
file as well to touch the actual hardware and not just information in the OS
cache.
Having more robust volume failure detection will be required when the container
scanner is enabled, because we do not want to mark large amounts of containers
unhealthy when the real problem is the disk.
