Hi- I know there is some work on ext4 regarding metadata corruption detection; btrfs also has some corruption detection facilities. The IETF NFS working group is considering the addition of corruption detection to the next NFSv4 minor version. T10 has introduced DIF/DIX. I'm probably ignorant of the current state of implementation in Linux, but I'm interested in understanding common ground among local file systems, block storage, and network file systems. Example questions include: Do we need standardized APIs for block device corruption detection? How much of T10 DIF/DIX should NFS support? What are the drivers for this feature (broad use cases)? -- Chuck Lever chuck[dot]lever[at]oracle[dot]com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
