If a user has exceeded the block soft quota and the grace period has expired, what happens?

If a user has exceeded the block soft quota and the grace period has expired, what happens?

• The soft limit becomes a hard limit until the user goes below the soft limit again
• The user will lose data, as files will be deleted automatically by the kernel.
• The question is invalid because users cannot exceed block soft quota limits
• Nothing, the user can still continue to use files as normal
