The combination of journalling, barriers, committing data safely to disk and VMs is complicated and does not always provide filesystem integrity on power failure, depending on many factors. However, if you see corruption only with 2.6.30 and later, but not with 2.6.29, that does suggest a kernel problem. -- Jamie -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
