I''ve been running BTRFS for a while testing out various stuff, and I''ve found it to be quite stable (although reading this list makes me realize how much activity there really is).. I just hit my first bump in the road, and I wondered if someone could give me a hint how I can gather enough information to be useful here. Basically, the filesystem I''m running is a 2 disk

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

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

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

I was looking through some of the archives and notice a patch submitted to implement: btrfs subvolume show <path-to-subvolume> command. I also noticed that is does not appear to be in the git. This looks like a useful capability. I was trying to find out what the UUID was for a newly created subvolume and have not found out how to do that. Gene -- To unsubscribe from this

When mounting a subvolume by name, mountinfo shows the name of the subvolume. When mounting a subvolume using subvolid it does not. Seems like a problem when trying to determine what is mounted. -o subvol=<name> # cat /proc/self/mountinfo | grep vda 43 34 0:29 /home /home rw,relatime shared:29 - btrfs /dev/vda1 rw,seclabel,space_cache 44 34 0:29 /boot /boot rw,relatime shared:30 - btrfs

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 Chris and everyone else, First let me congratulate you for the nice job on btrfs. I've been stress testing it with parallel kernel compiles intermixed with snapshot taking, up to about ~100 load avg on a dual core box and it's doing quite well :-) I noticed that when creating snapshots it seems to always snapshot an entire subvolume, that is if one does: test1:/mnt# btrfsctl -s

Hi, Let me know if this is the wrong place to ask... I''m using Fedora 12 x86_64, mostly with the newer 21.6.32 kernel, and have a single btrfs filesystem within a 120Gb partition. I''d like to extend the space btrfs can use. One option is presumably add a new device to btrfs, but I was hoping to simple resize the existing partition to say 160Gb. With ext4 I might do

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

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

This fixes the issue I had come across with the default subvolume not being set/used on btrfs when isntalling via `extlinux --install /boot/syslinux`.

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

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

NFS needs a unique identifier for a filesystem to be able to export it. This can be set by the admin (fsid= in /etc/exports) but that is a hassle and it is best to set it automatically. nfs-utils currently uses the UUID returned by libblkid if that works, or the fsid returned by statfs64 if libblkid finds nothings and fsid is non-zero. Otherwise it uses device major/minor. This

Is btrfs subvol support failing just for me?

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 |
