Just dealt with a pesky VM snapshot issue in a VMware ESXi setup—trying to restore a large Windows VM from a backup, but it kept failing with "insufficient disk space" errors on the datastore, even though space looked fine.
Turns out, the snapshot chain was corrupted from a power blip during creation. Fix: Used vim-cmd vmsvc/snapshot.remove to clean up dangling snapshots, then consolidated with vmware-cmd <vmx> consolidatesnapshots. Freed up hidden blocks and restored smoothly.
Pro tip: Always verify snapshots with esxcli storage vmfs snapshot list before big ops.
Hit similar snapshot snags? How'd you resolve?
