Abstract
A processing device receives a request to delete a snapshot of a virtual machine. The processing device identifies a volume chain of a virtual disk in a shared storage that includes a destination storage volume and a source storage volume. The snapshot is associated with the source storage volume or the destination storage volume. The processing device instructs a host machine to perform a merge operation to merge data of the source storage volume with data of the destination storage volume and to delete the snapshot. The processing device monitors a set of writable storage volumes that comprises the destination storage volume to determine whether a storage threshold for any storage volume of the set of writable storage volumes is met during the merge operation. In response to the storage threshold being met during the merge operation, the processing device causes the performance of an extension operation to extend the allocated disk space of at least one storage volume of the set of writable storage volumes.
