I am using FileVault 2.0 on Mavericks.
After restarting the computer one day, I was presented with the gray file vault login screen (normal). After typing in a password, it begins the login process, but then after 20 seconds or so, a spinner shows up below the account image. This spinner continues spinning indefinitely (the most I have waited at this screen is 30 minutes).
If I try holding down the power button and attempting to login again it fails no matter which user account I try.
I tried using Disk Utility to verify my disk and it shows that it is fine.
How do I fix this problem?
