A snapshot of a windows 5.5 vCenter was taken before a minor update.
The admin forgot the remove the snapshot days later.
Deletion of the snapshot only ends up working for the OS disk. A “Virtual Machine disks consolidation is needed” appears for the VC VM.
Since there are no backups at the datastore layer (VMDK) the plan is to hot clone the VC VM before running the consolidation task as the backup.
The hot clone fails with “error occured while saving the snapshot msg:snapshot.error-QUIESINGERROR” due to heavy IO.
The game plan is to shut down the VC VM. Connect to the ESXi host that the VM is register to and cold clone the 2nd disk drives VMDK as the backup. Then run the consolidation task via the c# client while the VM is power off.
