Issue Description

While deriving resources from the VDC, selecting a storage location prompts an error indicating that the storage is either offline or insufficient. Although the available space is 445GB, the storage utilization is 91%. When acquiring resources, VDC specifically marks storage B as offline or insufficient.

Error/Warning Information

Handling Process

  1. Check the storage status on the VMP. Both local storages appear normal.
  2. Deploying a virtual machine from the VMP is possible, but an alarm is triggered, as shown in the attached figure.

Root Cause

When the VMP creates a virtual machine and selects the storage location, it calls the storagetree interface.

  • A returned status of 1 indicates normal operation.
  • A status of 5 indicates that storage utilization exceeds 90%.

In this case, the VMP displays a prompt message but still allows virtual machine creation. However, the VDC detects that storage usage exceeds 90% and prevents the deployment of virtual machines.

Solution

  1. Go to VMP backend, vim /usr/share/perl5/VTP/VAPI/Storage/Vtpconfig.pm

  2. Modify the value of STORAGEALERT from 0.9 to a higher ratio, for example to 0.92.

Suggestions

This modification is applied under special circumstances. Typically, when storage usage reaches 90%, the recommended solution is to advise the customer to expand the storage capacity.
