A different kind of suicide
It is official by now that there are maniacs out there who already migrated their root-filesystem on BTRFS. So why not joining those freaks?
Theoretically it shouldn’t be a big hassle: Boot a Live-CD, mount and backup the Linux partitions including their permission stuff to prevent breakage and dangle the Windows space in shape as you already have your hands on it and migrate to BTRFS. Theoretically.

Copy On Write?
March 16th, 2008 by Stargazer
While browsing my documents for BTRFS stuff, which was recomended by Rei, I came across a funny term named ‘Copy on Write’.
I guess, you’re already shaking your head, asking yourself what the heck I would copy on write – but be sure, I know what I am talking about. We are talking about memory management on modern IT systems.

BTRFS 0.13 is out!
February 22nd, 2008 by Stargazer
Chris Mason released a new btrfs release where he corrected some bugs – the nastiest one was a checksumming bug. But the thing you’ll notice most, are the speedups.

Btrfs News
February 6th, 2008 by Stargazer
It’s quite a while since the news on btrfs, Chris Mason is working on. Since Toei Rei offered her ebuilds for our Overlay, btrfs is even in use here and it has been proved, that there are no great problems. Today she told me some hint she picked up while talking to Chris Mason. For displaying the subvolumes on a partition, mount its subvolume ‘.’:
mount -t btrfs -o subvol=. /dev/xxx /mnt/btrfs
The mountpoint used above contains now a read-only filesystem, having the subvolumes as directories (which are writable then).

Surprise, surprise

You remember the Btrfs project, the new and really fast filesystem? Rei – a fellow gentoo user tests this filesystem on her computer and discovered a nasty bug causing a kernel panic. She reported to the mailinglist.
The bug was already fixed in the Mercury-Repository – so she did some Live-Ebuilds. Well done!

BTRFS 0.8 is out
September 17th, 2007 by Stargazer
You’ve read enough about the road trip? Good news: this posting here isn’t about. Honestly, it was fun without a pc, but kind of strange. So back here I was checking for updates and as far as I can see, Chris Mason released a new version of his btrfs.
So what’s new? The most important change for me is, that the subvolumes can be mounted directly by now – so you’re able to use them without great symlinking tricks to get everything in place. So how’s it done? The mount command:
mount -t btrfs -o subvol=mysubvol /dev/with/btrfs /mount/point

There’s a new Filesystem in town: BTRFS
July 3rd, 2007 by Stargazer
On the 12th of July Chris Mason mailed to the lkml.org mailinglist introducing his new project, a filesystem for a Datacenter, called BTRFS. Although we are not talking about a final version, the technical specifications are looking great. If you want to have a look at the current status, feel free to check out the downloads. Chris Mason is a member of the Oracle Linux Kernel Team.
Anyways, my Linux desktop here has to suffer for it. Having the Gentoo portage tree on its own partition it is possible to test the new filesystem under real world conditions.
