similar to: System Rollback With Btrfs in Fedora 13 announced

I thought I would try btrfs on a new installation of f14. yes, I know its experimental but stable so it seemed to be a good time to try it. I am not sure if I have missed something out of all my searching but am I correct in thinking that currently: I. it is not possible to boot from a snapshot of the operating system and, in particular, the yum snapshots cannot be used for

I have a 1.5 TB (1,475,720,773,632) partition that I wanted to convert from ext4 to btrfs. It is currently used as / for ubuntu 10.10. I booted into 11.04 beta2 and tried a ''btrfs-convert /dev/sdc1'', but after about 20 minutes it segfaulted. I performed a: sck.ext4 -cDfty -C 0 /dev/sdc1 After everything was clean, I downloaded the debugging symbols for btrfs-convert and

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

Hi all, I suffered a lot for the terrific performance of aptitude on a BTRFS filesystem. I don''t think that BTRFS is a slow filesystem, but it seems that some aptitude (or dpkg) patterns are capable to highlight the btrfs slowness in some corner case. In order to alleviate this problem, I wrote a small script which calls aptitude with the LD_PRELOAD libeatmyadata library. And now I

Hi. I''m considering an imminent switch from ext4 to btrfs and I''m hoping that someone can lend me advice before I do something unsupported. I have a software raid 6 array configured via mdadm. It was sitting at 8 x 3TB until I recently doubled that, grew the array and found that ext4 doesn''t want to resize. So, I''m looking to: 1. convert from ext4 to btrfs

The condition can be relaxed to accept also 0 which will delete unoccupied chunks and does not need space for the actual data relocation.

Hi, I try to format a USB memory with a Btrfs. I can format it with mkfs.btrfs without problems. But; when I try to mount it, it fails to mount with the below error messages. But the USB memory works fine with other filesystems (ext4, XFS etc.). So, the hardware is not faulty. tarkane@tarkane:~$ sudo mkfs.btrfs -d single -n 4096 /dev/sdb1 WARNING! - Btrfs v0.18-26-g0030f1d IS EXPERIMENTAL

We want ''btrfs subvolume list'' only to list readonly subvolumes, this patch set introduces a new option ''r'' to implement it. You can use the command like that: btrfs subvolume list -r <mnt> Changelog v2 -> v3: - re-implement list_subvols() - re-implement this read-only subvolume list function based on the new list_subvols() Changelog v1 -> v2: -

I noticed it was getting a bit full (~79%) and tried to do some cleanup by removing old snapshots. Immediately after, the filesystem went into read only mode. I then followed Hugo Mill''s advice (that was
