Disk Operations
Scenario 1: Disk Usage Is Too High
Cause
Check the metric Node Disk Usage Trend by Time Period. If disk usage remains above the 85% warning line for 30 consecutive minutes, disk usage is too high. Possible causes include:
(1) A large number of invalid data assets occupy disk space
(2) Dataset data was not cleaned in time
(3) The update method for large datasets is unreasonable
(4) Cache files, backup files, log files, offline upgrade files, and historical images occupy disk space
Troubleshooting Approach
We recommend troubleshooting as follows:
(1) Refer to Disk Usage Distribution by Node to understand disk space occupation and find the resources that occupy the most space
?Optimization Measures
a. If cache files, backup files, log files, offline upgrade files, and historical images occupy significant disk space, contact Guandata for manual cleanup. If business allows, adjust the automatic cleanup cycle for these file types.
b. If business datasets occupy significant disk space, follow the troubleshooting approach below.
(2) Refer to Datasets with No Consumption and Datasets Producing Invalid Consumption to identify low-value business assets without affecting business
?Optimization Measures
For these resources, we recommend phased offline removal. Phased offline removal means setting the dataset update mechanism to Manual and observing whether business is affected. If there is no impact, clean up and delete the resources.
(3) Refer to Top 20 Datasets by Storage Space to identify large datasets
Pay attention to datasets that occupy a large amount of storage space, where dataset storage space accounts for more than 5% of disk space. You can click the dataset name to jump to it.
?Optimization Measures
We recommend considering the following options to control dataset size without affecting business:
a. Determine whether the dataset needs frequent updates. If timeliness requirements are moderate, reduce the update frequency or adjust the update cycle.
b. Configure data cleanup for the dataset. Based on business needs, clean up and delete data that is no longer needed. Note that Data Cleanup applies only to datasets imported from files or connected from databases. View datasets, direct-connection datasets, and form-entry datasets do not support this feature.
