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

I think I have some failing hard drives, they are disconnected for now. stan {~} root# btrfs filesystem show Label: none uuid: d71404d4-468e-47d5-8f06-3b65fa7776aa Total devices 2 FS bytes used 6.27GB devid 1 size 9.31GB used 8.16GB path /dev/sde6 *** Some devices missing Label: none uuid: b142f575-df1c-4a57-8846-a43b979e2e09 Total devices 8 FS bytes used

Hello, I had a raid1 btrfs (540GB) on vanilla 3.6.3, a disk failed, and removed it at power off, plugged in a new one, partitioned it (to 110GB, by error), and added it to btrfs. I tried to remove the missing device, and it said "Input/output error" after a while. Next attempts simply gave "Invalid argument". I repartitioned, rebooted the system, and made the partition grow:

Hi List, so first the basics. I''m running Arch Linux with 3.13-rc2, btrfs-progs 0.20rc1.3-2 from the repo and I''m using a SSD. So I was having kernel panics with my USB 3.0 Gigabit card and was trying to get a panic output. These panics are intermittent and most often happen while using Chromium. Anyway so my system paniced while I was in Chromium. After the reboot Chromium

Hi, I have setup a RAID1 using 3 devices (500G each) on separate disks. After removing one disk physically the filesystem cannot be mounted in degraded nor in recovery mode. When putting the disk back in the filesystem can be mounted without errors. I did a cold-swap (powercycle after removal/insertion of the disk). Here are the details: - latest kernel 3.2.1 and btrfs-tools on xubuntu

Hello, I have created a btrfs filesystem with RAID1 setup having 2 disks. Everything works fine but when I try to umount the device and remount it in degraded mode, the data still goes into both the disk. ideally in degraded mode only one disk show disk activity and not the failed ones. System Config: Base OS: Slackware kernel: linux 3.3.2 "sar -pd 2 10" shows me that the data is

I''ve had a go at determining exactly what happens when you create a filesystem without enough devices to meet the requested replication strategy: # mkfs.btrfs -m raid1 -d raid1 /dev/vdb # mount /dev/vdb /mnt # btrfs fi df /mnt Data: total=8.00MB, used=0.00 System, DUP: total=8.00MB, used=4.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=153.56MB, used=24.00KB Metadata:

I tried to unmount a btrfs filesystem located in a external usb hard drive. This belonged to a raid1 data and metadata filesystem mounted in degraded mode. Unfortunately, I couldn''t save the image of filesystem but I could see this error in kern.log: Aug 4 02:23:55 rohan kernel: [ 3747.840027] usb 1-3: new high-speed USB device number 8 using ehci_hcd Aug 4 02:23:55 rohan kernel: [

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, this is a new attempt to improve the output of the command "btrfs fi df". The previous attempt received a good reception. However there was no a general consensus about the wording. Moreover I still didn''t understand how btrfs was using the disks. A my first attempt was to develop a new command which shows how the disks

Hi! The problem is that the BTRFS raid10 filesystem without any understandable cause refuses to mount. Here is dmesg output: [77847.845540] device label linux-btrfs-raid10 devid 3 transid 45639 /dev/sdc1 [77848.633912] btrfs: allowing degraded mounts [77848.633917] btrfs: enabling auto defrag [77848.633919] btrfs: use lzo compression [77848.633922] btrfs: turning on flush-on-commit [77848.658879]

Creating a btrfs file system using btrfs-progs-0.20.rc1.20130308git704a08c-1.fc19, and either kernel 3.6.10-4.fc18 or 3.9.0-0.rc3.git0.3.fc19, makes a file system that cannot be mounted by kernel 3.6.10-4.fc18. It can be mounted by kernel 3.8.4. I haven''t tested any other 3.8, or any 3.7 kernels. Is this expected? dmesg reports: [ 300.014764] btrfs: disk space caching is enabled [

Very low priority. No user data at risk. 8GB virtual disk being installed to, and the installer is puking. I''m trying to figure out why. I first get an rsync error 12, followed by the installer crashing. What''s interesting is this, deleting irrelevant source file systems, just showing the mounts for the installed system: [root@localhost tmp]# df Filesystem

Hi, I have a home server on Linux Arch (kernel 3.11.2) that uses multi-device btrfs on root filesystem. Until recently it worked completely fine. And yesterday I rebooted it and the machine did not wake up. I booted from a USB (kernel 3.10) and tried to mount the filesystem.
