Disk Health Monitoring

What is Disk Health Monitoring?
Disk Health Monitoring, an innovative feature within TOS 6, protects your data from possible disk failures by consistently monitoring the health status of disks. This proactive approach facilitates early issue detection, empowering you to promptly take actions like backing up data or replacing troublesome hard disks.

How does disk health monitoring work?
The disk health monitoring workflow unfolds through the following steps:
Initially, the system autonomously identifies and defines crucial health attributes for both mechanical hard drives and SSDs, establishing safety thresholds for these attributes. As TOS operates, the system daily queries the S.M.A.R.T. information of each disk and scrutinizes the values of key attributes. Upon detecting that these values surpass the set thresholds and the disk's health status has undergone changes compared to the previous assessment, the system automatically updates the disk's health status. Notifications are then disseminated through desktop messages and email alerts.
It's important to note that this feature is activated by default and operates seamlessly without requiring manual intervention.

How should I interpret disk health monitoring alerts in TOS 6?
The alerts are categorized into three states: "Normal," "At risk," and "About to crash," each with specific explanations:

1. Normal:
This state indicates that all key attributes of the disk are within the normal range, reflecting a good health status. However, it's important to note that since there is a large number of S.M.A.R.T. attributes for disks, the system cannot monitor every attribute. Therefore, a normal status of key attributes doesn't guarantee the normalcy of all attributes. Major faults outside the key attributes can still lead to disk damage and data loss.

2. At risk:
This state signifies that one or more key attributes of the disk show abnormalities. While it doesn't necessarily mean imminent disk damage, it's crucial to back up data and closely monitor the further development of the disk health status. If the key attributes continue to worsen, prompt disk replacement is recommended.

3. About to crash:
This state indicates a serious deviation of one or more key attributes beyond the normal range. If the situation persists, the disk is on the verge of failure. Disks in this imminent failure status must be replaced immediately to prevent data loss.
Understanding and responding to these alert states is crucial for maintaining the integrity of your data and ensuring the reliable performance of your storage system.
