Git index getting corrupted Follow
Answered
This has happened twice due to a power outage, my Git index gets corrupted. I am using a repo in a Linux VM, hosted on a Windows 7 system. That repo is also the root project for IntelliJ. Git tells me "index file smaller than expected". How can I prevent the corruption again? Is it inherent of how my code base and workspace is set up?

In the described thread the issue was the possible race between commands IDEA issues and the command user executed manually.
In your case, as you said, this is a power outage. Probably power went downs during executing some commands that update git index file.
I don't think there is anything we can do here, except preventing power outages.
On the other hand, the setup you described can also affect this. Mapped directories, even from a local VM, can have latency workign with them, as a result git commands may take longer then usual.
