Zusammenfassung:An implementation of the disclosure provides a system comprising a memory to store disk images and a processing device, operatively coupled to the memory. The processing device is to identify a first disk image comprising a volume chain. Each volume in the volume chain comprises a respective metadata file. The identified first disk image is to be deleted from a virtual machine (VM). Responsive to identifying the first disk image, a second disk image associated with the VM is generated. One or more volumes in the volume chain of the first disk image are isolated from an active volume associated with the VM. The isolated volumes from the first disk image are moved to the second disk image by updating the metadata file associated with each of the isolated volumes. Thereupon, the first disk image is deleted from the VM.
