[galway-lug] Btrfs

[Carles Sentis]

We all know the advantages of btrfs[1], it is getting at this point very fast and stable. Something to consider using seriously.

I had my system install for a few years now and I've been upgrading Ubuntu ever since. I'm using ext4 but I was thinking on perhaps converting my partition to btrfs[1].

So, I just like peoples opinion. Is it worth the hassle? There's even tutorial[2] on converting from extX to btrfs[1], although it doesn't say it on the tutorial[2] I would assume I would need to back up everything and copy back once the conversion is done.

Thought?

Linux 3.4 came out today. The updates and changes made to Btrfs are outlined here:
http://kernelnewbies.org/Linux_3.4#head-8ad9e3d4ad73e1da565f52c2abbe9acf7efdc614

To be honest, the fact that such rapid and sweeping performance-and-otherwise changes are still being made to Btrfs doesn't bode well with me. I'm still going to give it another year or more, or until the Canonical gods decide I should use it by default.

Hey, some people even still think ext4 is too experimental, and stick with ext3 as a result.

I saw the release of the new kernel yesterday and it was reading the changelog that made me think on btrfs again...

I want the latest and greatest... I want bleeding edge... I want wayland, btrfs, ... but I also don't my computer to crash... and this options are mutually exclusive.... grrrrrrrhhhhh!!!!

I've been using btrfs for an external disk for a while now, I've had a couple of kernel panics here and there when pulling the cable when it wasn't fully ready. My fault really, but it I think it should fail gracefully/silently rather than crashing the system. 3.4 should be pushed as an update to fedora tomorrow or soon at least, so hopefully that will be solved.

I had it as my main FS for a while. I don't remember having any major problems with it, but as I've got an SSD, ext4 was more performant by default at the time (this may have changed, not sure).

I say go for it if you don't have an ssd (although even if you do, you can probably tune it some, so that performance isn't an issue).

Ah Wayland... there be a better life on the horizon... some day.

We just got a Kernel update today and we still on 3.2. Perhaps once we the 3.4 I may think about this again.

At the same time I'm thinking. Why fix it if isn't broken? or is this me just getting lazy

Although BTRFS is a really cool f/s, with some excellent features, there's no way I would use it for anything but experimentation, right now.
I have done some playing with it, and the live snapshotting is pretty cool.For now, though, ext4 will do me fine.

Ubuntu won't get Linux 3.4 until 12.10. They'll just stay on 3.2 and release incremental updates and security patches every 6 weeks.
