A look at the PyPy 2.0 release
It's right in the definition of RAID5: you cannot expect to maintain data integrity after a double-fault. The filesystem used on top of it is irrelevant.
Ext3 and RAID: silent data killers?

Most people, myself included, expect a degraded RAID array to fail **only if another drive fails**. I do NOT expect losing 256KB of data because a single 4KB write failed.
And in fact, the array didn't lose it. It just can't tell which 4KB went bad, which it could if MD did good write-intent logging.
