| Symptom | Likely Cause | |---------|---------------| | VM fails to power on: "Unable to access VMDK file" | Missing or corrupt descriptor ( .vmdk ) file | | Flat VMDK exists (e.g., vm-000001-flat.vmdk ), but no descriptor | Descriptor deleted or overwritten | | Flat VMDK shows raw data (no partition table when inspected) | Corrupt partition table or damaged descriptor linkage | | VM snapshot consolidation fails | Orphaned flat VMDK from failed snapshot removal | vmware recover flat vmdk
This creates two new files: temp.vmdk (the new descriptor) and temp-flat.vmdk (a blank dummy disk). The boot sequence scrolled—white text on a black void
# Attach flat VMDK directly to a helper VM as a raw disk # Or use guestmount (libguestfs) guestmount -a vmname-flat.vmdk -m /dev/sda1 /mnt/point The ghost was back in the machine
Always ensure robust backup strategies (such as Veeam or native snapshots) are in place to avoid manual flat file recovery scenarios, which can be time-consuming and carry a risk of data overwriting if performed incorrectly.
Now you must point the new temp.vmdk to your original data file. Difference between .vmdk and -flat.vmdk | VMware vSphere
of the flat file: ls -l *-flat.vmdk . Note: Record the number exactly (e.g., 4294967296) . 2. Create a Template Descriptor
