Linux InternetNews talks to developers and vendors about the rise of Btrfs as a successor to Ext4. Though Ext4 adds extents, Chris Mason, Btrfs developer noted that BTRFS adds a number of other features beyond that. Among those features are items like snapshotting, online file consistency checks and the ability to perform fast incremental backups. BTRFS (pronounced better FS) is currently under development in an effort led by Oracle engineer Chris Mason. With the support of Intel, Red Hat, HP, IBM, BTRFS could become the engine that brings next generation filesystem capabilities to Linux.

Please elaborate how you go about fixing something you can't even detect?

The odds are that you can't fix it anyway, so you're screwed either way - unless you have redundancy regardless. If you have redundancy then that's the only way you will be OK. Either that or you use an OS with decent device drivers or change your hardware ;-).

Again if you have no clue it is happening how do you go about fixing it?

You use something that works to start off with, or you switch mighty quick. Whatever happens, you're screwed without redundancy no matter what silent corruption you think you've detected, or what you can't detect either.

Again if the end user can't detect corruption since it is "silent" how does one inform the developers or hardware guys?

Users can't inform the developers or hardware guys because you won't know what has been detected at all and won't be able to give them anything. It will only be useful as a troubleshooting tool for developers to work through something that is reproducible.

The only place it hasn't generated any excitement is in your head. Everyone else including BTRFS developers and Gentoo developers took notice and are doing something about it. Meanwhile you are still trumpeting a very flawed view point.

Yer, it's created a moderate amount of excitement - amongst developers. They will use it to recreate scenarios where corruption has taken place, find out what has happened in various device drivers and/or inform hardware manufacturers what has been going wrong with their hardware. Users will feel the indirect benefits of it but they will carry on as they have always done because they can't do much about it.

CERN did silent data corruption research and found it to be a major problem.

Good for them. Did they actually go through 20TB of their own data and actually find out how much corruption they had, did they actually fix anything or did they just produce some numbers? ;-)
