+This is my last segment on the file system.
+There's a new thing out there and I'm really not so new but it's called BTRFS and it's been a
+pretty big thing. It's supposed to be a really big deal and the commercial Linux
+distributors are supposed to have it as the default system.
+Unfortunately somehow XFS has come back and sort of pushed BTRFS out of the commercial realm
+and back into the hobby realm.
+It's a new copy on right or CWO file system for Linux and it implementing advanced features
+while focusing on fault tolerance. Repair and easy administration.
+It's been jointly developed by a number of companies. Sousa, HP, Red Hat, lots of different
+companies. BTFRS is licensed under GPL and open for contribution from anyone.
+Not too many companies have said that they are using BTRFS and production but we
+welcome those who can say they are production users on a following page.
+And so when I went to the Wiki it says BTRFS on various sleep analysis, it had lots of names so
+it's called ButterFS and that's what I heard on the Linux Action Show when they talked about it
+or betterFS or BTRFS or simply BTRFS and again it's GPL licensed experimental copy on right
+file system for Linux. Okay and of all places guys for all these Oracle haters out there,
+it started with Oracle in 2007 so and it's still heavily development and marked as unstable,
+especially when the file system becomes full. No space conditions arise which make it
+challenging to delete files. BTFRS is intended to address the lack of pooling snapshots,
+check sums and integral, multi-device spanning list of systems. So question why would you use
+BTRFS if the free ZFS is available now? That's just, you know,
+and it allows you to scale upward to larger file systems in the enterprise.
+Chris Mason is the principal BTRFS author and he's done a lot of work and I really wish
+that I could talk to him about why it's great and the differences between it and ZFS and XFS
+but I don't know if I'll ever find him. I'll have to Google him and see if he'll do an interview with me.
+Has a stated goal to let Linux scale. He said that it was a stated goal,
+stated the stated goal was to let Linux scale for the storage that will be available. So that's
+what the stated goal was to let Linux scale for the storage that will be available. Scaling is not
+just about addressing the storage but also means being able to administer and manage it with a
+clean interface that lets people see what's being used and makes it more reliable. In 2008,
+the principal developer of XT3 and XT4 file systems, his name is Theodore TSO stated that although
+XT4 has improved features, it's not a major advance and uses old technology and is stopgap.
+TSO believes that BTRFS is the better direction because it offers improvements in scale,
+build your reliability and ease of management. BTRFS also has a number of design ideas that were
+used in RISER 3 and RISER 4. Okay, I've used BTO for S and for BORI one time and it was okay.
+In the enterprise commercial space, I'm not sure why I would use it if I could use XFS or
+if I could use the ZFS for Linux option. All right, so this concludes my series. I hope that
+y'all enjoyed it. I really like to have these short features. I listen to a variety of podcasts
+and not very many of them go out and look at something and make it short and try to be concise with it.
+For instance, if you listen to the Linux outlaws, you have to go into it for almost an hour before
+you figure out what's going on in the podcast if you want to listen to it. Same thing with
+if you listen to Dan Washco and all those at the weekly podcast that's been on for five years,
+it's not really a concise thing so they don't say what they're going to talk about at the beginning
+of it. So it's more of a meeting between friends and they talk about beer or whatever and
+I'm sure that sometimes this is interesting. But if you really want to look at something,
+I'm not sure really that there's that many formats. I mean sometimes if you listen to
+the guy at StoneHinge.com that does floss weekly, you know you know within a minute or two if
+it's interesting for you. So I'm more than that camp to try to tell you upfront what I'm going to do
+and then if you're not interested you know the great thing about podcasts is you just click the
+next button. All right, hey if you have any questions or anything you can reach me at jwp5.html.com.
+I really appreciate your time and any feedback you might have that be more than welcome. All right,
+hey thank you very much. Bye.
