btrfs 0.13 and XFS comparison
Hi there, Just gave 0.13 a spin against XFS (both with default mkfs options) on my SATA tower and was impressed by how much performance has improved since last time I played with it (v0.5)! It pretty much matched XFS for I/O performance and had much better file creation/deletion performance.

btrfs balancing start - and stop?
Hi, My company is testing btrfs (kernel 2.6.38) on a slave MySQL database server with a 195Gb filesystem (of which about 123Gb is used). So far, we''re quite impressed with the performance. Our database loads are high, and if filesystem performance wasn''t good, MySQL replication wouldn''t be able to keep up and the slave latency would begin to climb. This though, is

kernel BUG at fs/btrfs/volumes.c:3707 still not fixed in 3.7.1 (btrfs-zero-log required) but shown as "RIP btrfs_num_copies"
Unfortunately my laptop deadlocks from time to time, and too often it triggers this bug in btrfs which is quite hard to recover from. The bigger problem is that all the user sees (if anything) is seemingly unrelated info, namely, "RIP: btrfs_num_copies+0x42/0x0b" or somesuch It''s only if you have serial

btrfs filesystem balance /mnt/btrfs -> segmentation fault (kernel BUG at fs/btrfs/relocation.c:3296!)
I''ve enabled "extended inode refs" and "skinny metadata extent refs" with btrfstune. Then, I''ve tried running "btrfs filesystem balance" - unfortunately it segfaulted. (not sure if I should run balance operation after using btrfstune with -r and -x)? This is with 3.10 kernel with "Btrfs: make backref walking code handle skinny metadata"

[BUG] Cannot Mount Btrfs Volume Created By mkfs.btrfs v0.18-26-g0030f1d
Hi, I try to format a USB memory with a Btrfs. I can format it with mkfs.btrfs without problems. But; when I try to mount it, it fails to mount with the below error messages. But the USB memory works fine with other filesystems (ext4, XFS etc.). So, the hardware is not faulty. tarkane@tarkane:~$ sudo mkfs.btrfs -d single -n 4096 /dev/sdb1 WARNING! - Btrfs v0.18-26-g0030f1d IS

BUG btrfs fi show displays stale btrfs volume
I''ve filed this bug under util-linux, because I think wipefs isn''t deleting all btrfs metadata it could. But ultimately it appears to be a btrfs bug because nothing else sees the stale volume. btrfs-progs-0.20.rc1.20121017git92d9eec-1.fc18.x86_64 e2fs-progs-1.42.5-1.fc18.x86_64 kernel 3.7.1-2 Brand new 80GB

[PATCH] btrfs: fix parsing of output of 'btrfs qgroup show' (RHBZ#1188553)
'btrfs qgroup show' used to output bytes in raw, but in btrfs-progs v3.18.2 it outputs bytes with suffix KiB, MiB or like by default, which causes error when parsing the output. Fix it by adding '--raw' to let 'btrfs qgroup show' output raw numbers always. Signed-off-by: Hu Tao <> --- daemon/btrfs.c | 4 ++++ 1 file changed, 4 insertions(+)

[PATCH 0/2] Fix btrfs blocksize and bind mkfs.btrfs (RHBZ#807905). Currently if you specify the blocksize parameter to mkfs-opts with a btrfs filesystem, then it fails, because mkfs.btrfs interprets the -b option as meaning filesystem size. The first patch fixes this by disallowing blocksize (it cannot be mapped meaningfully into btrfs parameters). The second patch adds the full

[PATCH] daemon: use btrfs(1) to get btrfs labels
blkid(1) (or actually, libblkid) seems to handle file system labels up to 127 characters. Considering that btrfs labels can be up to 255 characters, this means long labels are not read correctly (i.e. get truncated) by blkid. Get the file system type, and if btrfs is available invoke `btrfs filesystem` to get the label of btrfs file systems. --- daemon/blkid.c | 6 ++++++

[PATCH] btrfs: add "no file data" flag to btrfs send ioctl
This patch adds the flag, BTRFS_SEND_FLAG_NO_FILE_DATA to the btrfs send ioctl code. When this flag is set, the btrfs send code will never write file data into the stream (thus also avoiding expensive reads of that data in the first place). BTRFS_SEND_C_UPDATE_EXTENT commands will be sent (instead of BTRFS_SEND_C_WRITE) with an offset, length pair indicating the extent in question. This patch
