Impact on the System

If the data disk or inode usage reaches 95%, the primary DN where the disk resides is restarted, and the standby and secondary DNs are forcibly stopped. If the log disk usage reaches 95%, DNs are not affected.

System Actions

None

Possible Causes

The cluster disk or inode usage exceeds 95%. As a result, the cluster becomes read-only and data cannot be written to or modified in the cluster.

Procedure

  1. Stop writing tasks immediately when the cluster is in the read-only state to prevent data loss caused by full disk space.
  2. Log in to the DWS console and cancel the read-only state of the cluster. For details, see Removing the Read-only Status.

    1. Log in to the DWS console.
    2. In the navigation pane on the left, choose Dedicated Clusters > Clusters. All clusters are displayed by default.
    3. In the Operation column of the target cluster, choose More > Cancel Read-only.
    4. In the dialog box that is displayed, click Yes to confirm and remove the read-only status for the cluster.

  3. After the read-only state is canceled, run the Vacuum command to delete unnecessary data. Click the cluster name.
  4. In the navigation pane, choose Intelligent O&M.
  5. Click the O&M Plan tab. Click Add O&M Task. For details, see Adding an O&M Plan.
  6. Perform the following operations on the Add O&M Task page:

    • Select Vacuum for O&M Task.
    • Set Scheduling Mode to Auto. GaussDB(DWS) automatically scans tables that require VACUUM operation.
    • Select System catalogs or User tables for Autovacuum.
      • If there are a large number of UPDATE and DELETE operations, select the User tables.
      • If there are a large number of CREATE and DELETE operations, select System catalogs.

  7. Click Next: Configure Schedule to configure the schedule and Vacuum type. You are advised to select Periodic for Task Type. The GaussDB(DWS) automatically executes VACUUM in your selected time windows.

    For automatic Vacuum O&M tasks, the system uses the VACUUM FULL operation to process user tables. VACUUM FULL holds a level 8 lock, which blocks other transactions. Other transactions will be in lock waiting during VACUUM FULL execution. After 20 minutes, a timeout error is reported. Therefore, do not perform other transactions in the configured time window.

  8. After confirming that the information is correct, click Next to complete the configuration.

Alarm Clearance

This alarm is automatically cleared after the fault is rectified.
