believe it or not, but it happens a lot really.

2 classic cases :
- logs on an SQL serveur. to clear the logs you have to merge the logs with the main DB file.
- snapshots on a Virtual Machine. It creates two files than needs to be merged eventually.

Those merging operations needs twice the space as the separate files. The process can start but if there is not enough space, it would fail and all the files would be corrupt. You need space to restore the backup but at this point there is any. it's a catch 22.
Restoring a backup needs space wich is a problem if the backup is on the same disk as it was the case here.

Also, by default, Microsoft SQL server stores it's files on the system partition. So if the company maintaning it didn't payed attention, the problem would be even worse, the OS would crash.

Did they forget to empty the recycling bin?
"Going forward, we will review our maintenance procedures and strengthen our efforts to prevent a recurrence, so that we can deliver as many vehicles to our customers as soon as possible," the unsigned note reads.

I think you're closer than you realize.

I bet it's something REALLY stupid like not clearing up IIS logs or some base-level datastore over-provisioning type of problem in vmwareland.

Or maybe a DB issue.

The fact that they call out a maintenance procedure pretty much says it all.
