Issue/Introduction

This article provides a way for customer to remediate the datastore out of space problem.

Symptoms:
Datastore is out of space while the total size of all VMs doesn’t exceed datastore capacity.

Environment

VMware vSphere 7.0.x

Cause

The VM backup may take long time to complete. While the backup is running, the VM disk are locked.
If a storage vMotion is performed while the VM is being backed up, the VM disk can’t be removed from source datastore.
After the backup is complete, these VM disks need to be manually removed.

Resolution

  1. Customer should avoid VM storage vMotion for the VMs being backed up.
  2. Customer may find the VMDKs not associated with the VM and FCD, then remove them to free the space.
