> Linux system gives the *"No space left on device"* exception in two cases.
> # Disk space is not available
> # Linux inode limit is exceeded
> NameNodeResourceChecker currently only checking the disk space, it should
> check the inode limit also.
> We got *"No space left on device"* exception even disk space was there and
> roll edit operation is failed. After analysis we found that Inode usage for
> the system is 100%.
