Hallo, linux-btrfs, I''ve (once again) tried "add" and "delete". First, with 3 devices (partitions): mkfs.btrfs -d raid0 -m raid1 /dev/sdk1 /dev/sdl1 /dev/sdm1 Mounted (to /mnt/btr), filled with about 100 GByte data. Then btrfs device add /dev/sdj1 /mnt/btr results in # show Label: none uuid: 6bd7d4df-e133-47d1-9b19-3c7565428770 Total devices 4 FS bytes

I''ve just confirmed this test failure by building and running coreutils'' "make check" on a btrfs file system I''d just created using mkfs.btrfs v0.19 on Fedora

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 EXPERIMENTAL

Hello all, I recently had a power failure and can no longer mount my /home directory. The harddrive has two BTRFS partitions: sda7(/) and sda8(/home). The / partition loads up just fine, but /home does not. I''ve tried btrfsck as shown below and I''ve included dmesg pertaining to btrfs. This is on ArchLinux and the software versions are as follows: btrfs-progs-unstable

Hi. I''m considering an imminent switch from ext4 to btrfs and I''m hoping that someone can lend me advice before I do something unsupported. I have a software raid 6 array configured via mdadm. It was sitting at 8 x 3TB until I recently doubled that, grew the array and found that ext4 doesn''t want to resize. So, I''m looking to: 1. convert from ext4 to btrfs

Hi, Doing some extensive benchmarks on BTRFS, I encountered a kernel bug in BTRFS (as reported in dmesg) Maybe the information below can help you making btrfs better. Situation Doing an intensive sequential write on a SAS 3TB disk drive (SEAGATE ST33000652SS) with 128 threads with Sysbench. Device is connected through an HBA. Blocksize was 256k ; Kernel is 3.3.0 (x86_64) ; Btrfs is version

I''ve run a little wired benchmark on comparing Btrfs v0.19 and XFS: There are 2000 directories and each directory contains 1000 files. The workload randomly stat a file or chmod a file for 2000000 times. And the number of stat and chmod are 50% and 50%. I monitor the number of disk read requests #Disk Write Requests, #Disk Read Requests, #Disk Write Sectors, #Disk Read

We want ''btrfs subvolume list'' only to list readonly subvolumes, this patch set introduces a new option ''r'' to implement it. You can use the command like that: btrfs subvolume list -r <mnt> Changelog v2 -> v3: - re-implement list_subvols() - re-implement this read-only subvolume list function based on the new list_subvols() Changelog v1 -> v2: -
