Can’t create or edit a file – Linux – but have diskspace?

Have you ever had a linux server or desktop which all of a sudden couldn't create a file - running "df -h" shows you your disk partitions aren't full? You've logged in as root to check - and yup you still can't write any files - even a "touch test.txt" fails with a message saying can't write file - disk or partition full?

Adding a new swap partition – Linux

I realised after my previous post I realised that it would be worthwhile talking about adding a new partitition. The first thing you need - or I assume - is that you have a separate hard-drive which is not active (mounted) or can be unmounts using the standard umount command. We assume the device is sdc (it could be sdb, sda, hda1 etc..).
