Find which VM has snapshots on datastores
Problem: Many VMs had snapshots not listed in snapshot manager but still existed on the filesystem.
Solution:
Find all the snapshots on the datastores and clean them up by either cloning the virtual machine or command line tools.
Run this command on a host that has access to all the datastores you wish to scan.
find /vmfs/volumes/ -name “*delta*” -type f -print0 | xargs -0 du –human-readable –total|less
