Introduction

When you initiate a Delete or DeleteAll operation on snapshots, the snapshot is immediately deleted, then the backing virtual machine disk .vmdk files are consolidated on-disk. If the consolidation fails [during snapshot deletion], some Virtual Disk files may remain on disk and/or be actively used on the Datastore, consuming storage capacity. (Source: VMware).

...

Note

Additional space is temporarily required to perform the operation. Consolidation can be I/O intensive, it is advisable to invoke this operation when guest is not under heavy I/O usage.
