Issue

Use this article to troubleshoot cases in which a standard ZSphere user cannot resize a VM disk.

Symptoms

• A non-admin standard user cannot resize a VM disk.
• The user's permissions and quota appear normal.

Environment

• Product: ZVF
• Version: 4.x
• Component: ZSphere
• Affected object: permissions/quotas
• Scenario: Permission and authorization issues. Confirm the current version, deployment topology, storage type, and operation timeline.

Possible causes

• The standard user lacks permission to query data store information and cannot obtain capacity information.
• Disk expansion depends on multiple capabilities, including storage-capacity queries, VM/volume permissions, and quotas.
• The permission model in the current version has a boundary that requires additional role permissions or a version fix.

Resolution

Perform the following checks in sequence, and record the affected objects, occurrence time, complete error messages, and current state.

1. Confirm the user role, project/account ownership, volume ownership, and quota.
2. Reproduce the issue as an admin and as the standard user, then compare failed API permission items.
3. Check whether data-store query permissions are missing.
4. If this is confirmed as a version issue, add the required permissions or track the fixed version as recommended by ZStack technical support.

Remediation

1. Add the permissions required to query data stores to the standard user role, or adjust role authorization based on the permission model of the current version.
2. If the required permission cannot be determined, provide the user role, failed API, and version information to ZStack technical support for confirmation.

Verification

• The standard user can view capacity information for associated data stores.
• With sufficient quota, the standard user can successfully resize disks of owned VMs.
