A very simplistic explanation of an i-node is like sectors in a Windows FAT filesystem. You may have 2000 megabytes available on a disk (or partition). You have 1000 i-nodes (or sectors) on that disk. Thats means that the smallest chunk of data on your disk would take up 2 megabytes. So, if you have 1000 files, each one megabyte in size, even though your disk is technically only half-full, you've used all 1000 i-nodes. This is what has happened to you, at least on that filesystem (partition). Normally you should find a good balance of i-nodes to space, but you can't have TOO many i-nodes without a large performance problem - that's why there's a limit.

Look for lots of small files on your root filesystem ("/") - that'll will probably be your problem. You can see that it's 93% used.
