Hello, recently I installed a distribution I want to look at via chroot into a btrfs subvolume on a multidevice btrfs. Now I tried to boot this, the kernel command line in GRUB looks as follows so far: /kernel-2.6.29-rc7-git3 root=/dev/sdb7 rootfstype=btrfs rootflags=device=/dev/sda1,subvol=archroot This gives "VFS: cannot find sdb7 or bad block", like it would when trying to mount via fstab wit...

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. The fstab entry: /dev/disk/by-id/scsi-SATA_ST31000333AS_9TE12DSC-part7 /mnt/btrfs btrfs defaults 1 2 Now after boot I get: ---- device fsid c4822885057410c-d2d65a83c2f15fb4 devid 1 transid 73034 /dev/sdb7 btrfs: failed to read chunk tree on sdb7 ---- So I have

Currently, extlinux does not support multi-device BTRFS volumes. Is anything planned to add this support? I believe I understand that it has to be a lot more complicated with multi-devices because you are doing the device I/O at a very low level. However, grub2 does support booting from multi-device BTRFS volumes (actually subvolumes on multi-device BTRFS volumes). I cannot be impossible

...ch sits on top of cryptsetup Luks device which subsequentely sits on top of mdadm RAID-6 spanning a partition on each of 4 hard drives (I know that it is sub-optimal setup). The backups/20130101-192722 is a read-only snaphot which I estimate contain ca. 100GB data. The /mnt/tmp/backups is btrfs multidevice raid10 filesystem, which is based on 4 cryptsetup Luks devices, each live as a separate partition on the same 4 physical hard drives that ultimately make the /mnt/adama-docs. Both btrfs filesystems are mounted with -o compress, and the /mnt/adama-docs is also mounted with noatime. I suspect th...

Some programs like btrfsck should not be run on a mounted filesystem. This patch adds a check in btrfs_open_devices() for the mount status of every device belonging to the filesystem. The function check_mount() gets improved support for loopback devices. It now detects if the program is run on the file that is being used by the loopback device. Signed-off-by: Andi Drebes

Hello Digvijoy, > Does your kernel have inbuilt support for Logical Volumes > ,because your ouptut shows VFS is unable to mount root ,which > means dm-mod and multidevice modules wasnt compiled into the kernel. Multi-device support is compiled into my DomU kernel, device-mapper is built as a module. But I don''t think this has something to do with my problem because I''m exporting 2 logical volumes, not the LVM physical disk, so my DomU kernel shou...

Hello everyone. Please, find the patch for Fedora 10 in the attachment(**). The distro-independent package will be put to kernel.org a bit later. I. Loading kernels from btrfs volumes Now you can load kernels and initrds from btrfs volumes composed of many devices. WARNING!!! Make sure that all components of your loading btrfs volume(*) are visible to grub. Otherwise,

Does anyone here use a multi-button (as in more than 2) mouse with Linux? How well supported are they? I've had to get one recently for work. I was diagnosed with CTS and I now wear braces and use a wireless Intellimouse. Works great at work with Windows, but I'm unsure how much, if any support there is for Linux. Anyone have experience with this? Preston

I''ve created a test volume and copied a bulk of data to it, however the results of the space allocation are confusing at best. I''ve tried to capture the history of events leading up to the current state. This is all on a Debian Wheezy system using a 3.10.5 kernel package (linux-image-3.10-2-amd64) and btrfs tools v0.20-rc1 (Debian package 0.19+20130315-5). The host uses an
