-----------------------------------------
Summary: Do not store disks_info in DB. Store it as dynamic info
in memory that can be used to show on the UI.
Key: AMBARI-3793
URL: https://issues.apache.org/jira/browse/AMBARI-3793
Project: Ambari
Issue Type: Bug
Components: agent
Affects Versions: 1.4.1
Reporter: Vitaly Brodetskyi
Assignee: Vitaly Brodetskyi
Currently, we store disks info in DB and this information is never updated
after registration. As disks details can change (space availability changes,
disks get mounted/unmounted, etc.) the persisted information is not useful.
We should instead hold the details in memory and refresh it at certain
intervals (e.g. once every 10 minutes) and then alert if space availability
hits some lower limit.
