Hakan, your script just ran me out of inodes, maybe you already had a 
fragmented file-system to start from and it triggered it faster.

Is there some specific output from debugfs.ocfs that will tell me when I 
am approaching the situation?

Right now I have a script running that does the following.

Create 1-3 small files, size between 1k and 7k, copy the small file, 
prepend some data to it then move it back on top of the original. Create 
a large file (starting at 20M and increasing 10k each time) then loop 
back to small files.

When the file system fills up I delete the oldest 20 large files and 
continue. That seems like it should cause some fragmentation. So far I 
am still been unable to reproduce the out of space error when I have 
free space and free inodes.
