Hi all. I have been running FS sanity on daily builds(glusterfs mounts only at this point) for a few days for a few days and I have been hitting a couple of problems:

Bonnie++ is just very slow(running for 10+ hours on 1 16 GB file) and FS mark has been failing. The bonnie slowness is in re read, here is the best explanation I can find on it:

Rewriting...done
This gets a little interesting. It actually reads 8K, lseek back to the start of the block, overwrites the 8K with new data and loops. (see article for more.).
On FS mark I am seeing:

How do we want to handle failures like this moving forward? Should I just open a BZ after I triage? Do you guys do a new BZ for every failure in the normal regressions tests?-b
