similar to: mkfs: specify subvolume for rootfs directory

Hi all, this patch include in /proc/mount the info about which subvolume is mounted and which metadata_ratio value is used. $ cat /proc/mounts rootfs / rootfs rw 0 0 [...] /dev/sdc /tmp/t4 btrfs rw,relatime,metadata_ratio=20 0 0 /dev/sdc /mnt/btrfs btrfs rw,relatime,degraded,metadata_ratio=20,subvol=snap- of-root 0 0 BR G.Baroncelli commit 3d7ea7bbd70a66c4d0f369b2879c503b722e8834 Author:

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 root".

Hi all, enclose a patch to improve the "btrfs subvolume find-new" command. This is a RFC because it is not finished, but it is an usable state and may be discussed. The aim of this patch is: - take in account not only an update of the extent but also an update of the inode and xattr (which includes the acl) - extract the generation reference number directly from a snapshot The new

Hello, I am having a problem with the second-generation of a custom isolinux boot CD for one of the PCs here in the lab. We have three types of PC here - two Dells and one from SGI (a SGI 230). The previous version of the custom bootcd still works on all three platforms. The new version only works on the Dells. It fails on only the SGIs with:

If we change our default subvolume, btrfs receive will fail to find subvolume. To fix this problem, we have three 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. 3.tell the user to mount the toplevel subvol by himself and run receive

The algorithm for btrfs subvolume search seems to be completely braindead, and at least in the current Linux kernels there are ioctls

Everyone: hello , i have a question when i boot from the xen built on 3.0.4source code which made i stumble on mounting rootfs , i get it panic when it can not open rootfs . my disk is sata disk of WD 250G ,and i built all the source code in ubuntu feisty amd-64 platform on gcc-3.4.1 compiler . First time i doubt whether i am not compile the ext3 file system in the xen kernel (my rootfs is

Hi, i am having problems converting the rootfs - I created a journal and booted with "rw rootflags=journal=<inode>" - Before i changes the fstab and put the WIP fsck to /sbin/fsck.ext3.

Hello All, I've recently encountered an issue with `extlinux --install /boot/syslinux` where a subvolume on btrfs which is set to `set-default` is not identified as the default subvolume. In my testing I pulled both the prebuilt binary from kernel.org which failed to identify that I had set a non 0 value via `btrfs subvolume set-default <id> <path>`. In extlinux/main.c there

Hello everyone, Laine Stump over at OFTC #virt was kind enough to point me to this email address. I am trying to run a LXC OS container with virt-manager and found out, that I need to create the rootfs with LXC/LXD and then point virt-manager to the rootfs location. ( I am running Ubuntu 16.04 inside a virtual machine [kvm] for testing) Both "lxc-create" and "lxc launch"
