similar to: btrfsctl -A not returning useful information

Hello, I''ve just pulled btrfs-progs from the new git repo git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git However, when I come to make it fails like so: gcc -Wp,-MMD,./.btrfsctl.o.d,-MT,btrfsctl.o -Wall -D_FILE_OFFSET_BITS=64 -D_FORTIFY_SOURCE=2 -g -Werror -Os -c btrfsctl.c gcc -g -Werror -Os -o btrfsctl btrfsctl.o ctree.o disk-io.o radix-tree.o extent-tree.o

E.g. btrfsctl -r -4000m /dev/sda5 results in: ioctl:: Inappropriate ioctl for device Distribution: Ubuntu 10.10 Kernel: 2.6.35-22-generic According to the Synaptic Package manager, the version of btrfs-tools is 0.19+20100601-3 Other information that can be of interest: - I started Ubuntu on a live CD - before invoking the btrfsctl command I invoked apt-get update. I have googled but have not

Good afternoon btrfs, I have been having issues with snapshots not reading the whole file tree below them. I have installed new btrfs-progs from git://git.darksatanic.net/repo/btrfs-progs-unstable.git made and installed them. My tree is: /Btrfs | |__ nfs1 | |__ data |

I found userspace tool, btrfsctl, uses BTRFS_VOL_NAME_MAX, and it also looks that this one is more proper. Kill BTRFS_PATH_NAME_MAX since no one will use it.

In snapshot destroy the dentry used for parent was the snapshot dentry itself. Remove d_invalidate since always return EBUSY, making possible to remove a snapshot using the btrfsctl -D option.

Hi all, I am using a single volume across two devices sdb7 and sda1, initially created on sdb7, and added sda1 using btrfs-vol later.

From: Anand Jain <anand.jain@oracle.com> (This patch is for the review/test not yet for the integration). Here is an implementation of the feature to add label to the subvolume and snapshots. Which would help sysadmin to better manager the subvol and snapshots. This can be done in two ways, one - using attr which is user land only changes but drawback is able to change the label

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

I''ve got a btrfs on an sd card, which I''m using as the root fs on a beagle. That''s not the problem :) The machine I generate my images on has an internal sd reader, and I also have a usb card reader. After creating the fs on the internal reader, I ended up plugging it in on the external reader. internal: sdd external: sdh mount /dev/sdh2 /mnt -t btrfs > mount:

Hi folks! Been using btrfs for quite a while now, worked great until now. Got power-loss on my machine and now i have the "parent transid verify failed on X wanted X found X" problem. So I can''t get it to mount. My btrfs is spread over sda (2tb), sdc(2tb), sdd(1tb). Is this something that an offline fsck could fix ? If so is the fsck-util being developed ? Is there a way to

Hi all, below a configuration for udev/initramfs which I propose to scan the block devices looking for a multi-volume btrfs filesystem. Btrfs has the capability to span a file-system on multiple device. In order to do that, the involved devices have to be "registered" in the kernel. In order to do that there are two options: # btrfs device scan <device> (or the old

I''ve just finished installing onto an OCZ Agilent v2 SSD with btrfs as filesystem. However to my surprise I''ve hit an ENOSPC condition one one of the partitions within less than a day of uptime, while the filesystem on that partition only reported 50% to be in use, which is far from the 75% limit people mention on the ML. Note that this occurs using a vanilla 2.6.32-rc5 kernel
