As of the latest updates to anaconda and grub2 for Fedora 18, it is now possible to install with /boot as a btrfs subvolume. The way that grub2 is handling this is the "reach down" to the files it needs as if the subvolume was a directory. Is this OK? At this point I am not worried about snapshots or any other complexities. If the subvolume name is known. should grub2 be able to

Setting subvolume/snapshot readonly has been missing for a long time. With this patch, we can set a subvolume/snapshot readonly via: o btrfs subvolume set-ro <path> Signed-off-by: Liu Bo <liubo2009@cn.fujitsu.com> --- cmds-subvolume.c | 40 ++++++++++++++++++++++++++++++++++++++++ ioctl.h | 7 +++++++ 2 files changed, 47 insertions(+), 0 deletions(-) diff --git

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

Hello, We are using btrfs filesystems in our infrastructure and, at some point of time, they start refusing to create new subvolumes. Each file system is being quota initialized immediately after its creation (with "btrfs quota enable") and then all subfolders under the root directory are created as subvolumes (btrfs subvolume create). Over time, these subvolumes may also be

I''m wondering is space really freed after deleting large subvolume? Will space be immediately available to other data like other subvolumes? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I have been experimenting exporting btrfs subvolumes over nfs. Main subvolume is filesys1 mounted at /filesys1. Below this is subvolume base, user1 is in base and documents is in user1. documents is mounted at /documents. /etc/exports is: /filesys1/base/user1 172.16.0.0/24(rw,no_acl,no_root_squash,fsid=0) /filesys1/user1-snapshot 172.16.0.0/24(rw,no_acl,no_root_squash,fsid=0)

Hi all, Just a quick question but can''t find an obvious answer. Can I create/convert a existing (btrfs) directory into a subvolume? It would be very helpful when transferring ''partitions'' into btrfs. I found a similar question way back in google, but that site is down now generally. Thanks in advance. -- To unsubscribe from this list: send the line

I''ve just pushed out a new integration branch to my git repo. This is purely bugfix patches -- there are no new features in this issue of the integration branch. I''ve got a stack of about a dozen more patches with new features in them still to go. I''ll be working on those tomorrow. As always, there''s minimal testing involved here, but it does at least compile on

I've just tried putting usr in a subvol. Installation proceeds normally, no errors, but I'm dropped to a dracut prompt which indicates mount of /usr failed. dmesg follows: [ 14.025215] systemd[1]: Starting dracut initqueue hook...

Hi, a recent Ubuntu upgrade killed my system. Luckily I had done a btrfs snapshot before, so I set the particular subvolume as default using # btrfs subvolume set-default 261 /mnt from a rescue system and was back up in no time. I then mounted the original volume with subvolid=0 and repaired it. So far so good. However, I fail to set the default volume back to the original. # btrfs subvolume

After a reorganisation of patches, and sending a bunch of them to Chris, I''ve also updated the integration branch to match that. It''s available from: http://git.darksatanic.net/repo/btrfs-progs-unstable.git/ integration-20110630 The shortlog of 17 patches in this branch beyond the ones I''ve sent to Chris is below. Hugo.

Is there a way to mix RAID 1 and 0 in different subvolumes? I am a new user to btrfs and would like to protect the important files with mirroring, but have a bulk area that is striped for speed and size. For example I want / and /home to be mirrored, but /media can just be striped as it is all data I can easily recreate. I see an item in the Project_ideas wiki entry called "Online raid

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

I am new to syslinux/extlinux. Can I boot from a linux btrfs subvolume? I am getting "Failed to load ldlinux.c32" when I attempt to boot from a btrfs subvolume. Setup: 1) I have a USB disk with one partition. The partition is marked "active". 2) I make a btrfs filesystem with "mkfs.btrfs /dev/sdd1". I mount the partiton and execute "btrfs su create

We create two subvolumes (meego_root and meego_home) in btrfs root directory. And set meego_root as default mount subvolume. After we remount btrfs, meego_root is mounted to top directory by default. Then when we try to mount meego_home (subvol=meego_home) to a subdirectory, it failed. The problem is when default mount subvolume is set to meego_root, we search meego_home in meego_root but can not

If we change our default subvolume, btrfs receive will fail to find subvolume. To fix this problem, i have two ideas. 1.make btrfs snapshot ioctl support passing source subvolume''s objectid 2.when we want to using interval subvolume path, we mount it other place that use subvolume 5 as its default subvolume. We''d better use the second approach because it won''t bother

Hello, This is the second attempt to bring in cross subvolume reflinks into btrfs. The first attempt was NAKed due to missing vfs mount checks and a clear description of what btrfs subvolumes are and probably also why cross subvolume reflinks are ok in the case of btrfs. This version of the patch comes from David and is in SUSE kernels since a long time, so it is tested and working. The patch

I am a relative newcomer to using extlinux. I am running Fedora 20 which means I am using syslinux 4.05. When I noticied that all of your documentation said that booting off ext234 and btrfs was supported, I gave it a try. Indeed, this does work with the boot files and the extlinux directory installed into the btrfs (root) volume. Has any thought been given to supporting supporting
