File I/O Errors:

File I/O Errors usually occur when the user doesn't have sufficient amount of storage space in designated system. 

Users are usually given a 7 days grace period if they are over quota and thorough this time the filesystem disables them from even editing their previously written files.If the user is not resolving the issue within the given grace period their login access will be totally denied.

All the filesystem write issues are storage quota related this also includes no space left on device issues.
