Hello everyone. This is the support for default single-device configuration. Subvolumes are _allowed_. Transparent compression is not allowed. Leafsize != 4K is not allowed. Nodesize != 4K is not allowed. Grub-0.97+btrfs doesn''t understand exotic things like preallocated extents (e.g. files composed by fallocate(2), posix_fallocate(3)). Also grub-0.97 doesn''t check btrfs

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

Hi Chris et al, Firstly, BTRFS is progressing at a very healthy pace and seems to be a fantastic filesystem so far, and pulled into 2.6.29-rc1 is fine news indeed. Is there any plan to add BTRFS support to GRUB (v1 or 2)? I''ve been unable to find any information so far... Many thanks, Daniel -- Daniel J Blueman -- To unsubscribe from this list: send the line "unsubscribe

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

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

I believe what I am going to write is a bug report. When I finaly did # btrfs send -v /mnt/adama-docs/backups/20130101-192722 | btrfs receive /mnt/tmp/backups to migrate btrfs from one partition layout to another. After a while system keeps saying that "Too many open files in system" and denies access to almost every command line tool. When I had access to iostat I confirmed the

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply

The variable ''last_index'' is calculated in the __btrfs_buffered_write function and passed as a parameter to the prepare_pages function, but is not used anywhere in the prepare_pages function.

Hello, I noticed a double definition of BTRFS_CSUM_TYPE_CRC32 in ctree.h and attach a patch that removes it. Best regards, Dirk

The commit 607d432d referred a static int array defined in ctree.h, and a static inline function (btrfs_super_csum_size) using this array, the obvious problem is every c file using that function would have a local copy of that int array, multiple c files calling would result multiple copies of that array: $ nm fs/btrfs/btrfs.ko | grep btrfs_csum_sizes 0000010c r btrfs_csum_sizes 00000114 r

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

What happens if you set an individual file inside a subvolume as nocow (chattr +C) and then take a snapshot of that subvolume and modify the file in both? Will btrfs now ignore the nocow attribute completely or will it do "as few copies as possible"? (I''d love to know if it''s possible to visualize the fragmentation of a single file.) -- To unsubscribe from this list:
