Since btrfs does not do recursive atomic snapshots (which I am ok with), I am doing this myself. A handful of suggestions/problems came up. 1. Maybe btrfsprogs could gain an option to do recursive non-atomic snapshots at the userspace level, simply invoking low-level atomic snapshots one by one? For the following, the kernel is 3.4.4 with the too-overloaded "0.19" version of btrfsprogs. 2. Subvolume directories are somewhat special, as you ma...

Hi Everyone, I am very new to this mailing list and very much interested in getting into the internals of BTRFS file system I was looking for mkfs.btrfs source code so that I can start getting how the disk is formatted with btrfs system. Can anyone of you redirect me to that place to download the btrfsprogs source code. Thanks in advance.

Creating a btrfs file system using btrfs-progs-0.20.rc1.20130308git704a08c-1.fc19, and either kernel 3.6.10-4.fc18 or 3.9.0-0.rc3.git0.3.fc19, makes a file system that cannot be mounted by kernel 3.6.10-4.fc18. It can be mounted by kernel 3.8.4. I haven''t tested any other 3.8, or any 3.7 kernels. Is this expected? dmesg reports: [ 300.014764] btrfs: disk space caching is enabled [

Hi, this series for libguestfs improves the support for OpenSUSE. There are couple of changes (in testing-only stuff) needed to help running the tests properly, and an update of the packagelist.

Hi all, we got a new test system here and I just also tested btrfs raid6 on that. Write performance is slightly lower than hw-raid (LSI megasas) and md-raid6, but it probably would be much better than any of these two, if it wouldn''t read all the during the writes. Is this a known issue? This is with linux-3.9.2. Thanks, Bernd -- To unsubscribe from this list: send the line

sorry forgot to follow the protocol, now included RFC in the subject. Hi, Appears that no one is working on the auto-snapshot feature for btrfs, so here I am implementing the same. Below is a draft on the feature list. Any comments / questions / suggestions are welcome, please do let me know. btrfs auto snapshot feature will include: Initially: - configurable timely

Hallo, linux-btrfs, please delete the option "-L" (for labelling) in "mkfs.btrfs", in some configurations it doesn''t work as expected. My usual way: mkfs.btrfs -d raid0 -m raid1 /dev/sdb /dev/sdc /dev/sdd ... One call for some devices. Wenn I add the option "-L mylabel" then each device gets the same label, and therefore some other programs
