Snapshot chain invalid — Inconsistent snapshot chain
Domain: Backup / VirtualizationPriority: Critical
What does this error mean?
A virtual disk or backup depends on a missing or invalid parent in the snapshot chain.
Likely causes
- A parent disk or descriptor was deleted
- A move or copy operation was incomplete
- The datastore filled up during snapshot activity
- Snapshot consolidation was interrupted
Checks and resolution
- Stop non-essential changes to the affected VM or backup chain.
- Inventory every descriptor and virtual disk in the chain.
- Verify CID and parentCID relationships where applicable.
- Work on a copy or open a vendor support case before editing descriptors.
Precaution: Do not edit VMDK descriptors without a backup and a clear understanding of the complete chain.
