Google Switching To EXT4 Filesystem
An anonymous reader writes "Google is in the process of upgrading their existing EXT2 filesystem to the new and improved EXT4 filesystem. Google has benchmarked three different filesystems — XFS, EXT4 and JFS. In their benchmarking, EXT4 and XFS performed equally well. However, in view of the easier upgrade path from EXT2 to EXT4, Google has decided to go ahead with EXT4."
We are still using ext2 on servers. Now I have an argument; if Google is still using ext2 maybe we aren't so foolish. We might update some day but it is not yet a priority. With UPS and proper fail over and backup procedure in place, I can't remember when a jounaling file system would have helped us in any way. They seem great for desktops/laptops although.
Everything I write is lies, read between the lines.
...or maybe the fact that he's no longer involved brings up questions about its future direction. I'm sure they took a look at reiserfs previously

I thought google had their own file system named the google files system.

I can't imagine why it would.
To the best of my knowledge, Google uses pretty much no Windows servers themselves(at least not for any of their public facing products, they almost certainly have some kicking around) and "a vast number of instances of custom in-house server applications" is among the least plausible environments for a Windows server deployment, so that is unlikely to change.
On the desktop side, Google has a bunch of stuff that runs on Windows; but it all communicates with Google's servers over various ordinary web protocols and stores local files with the OS provided filesystem. The benefits of EXT4 on Windows would have to be pretty damn compelling for them to start requiring a kernel driver install and a spare unformatted partition.
I suppose it is conceivable that some Google employee might decide to do it, for more or less inscrutable reasons; but it would have no connection at all to Google's broader operation or strategy.
They employ the main developer of ext2, ext3 and ext4.
He probably knows a lot about it.
New things are always on the horizon
