Hello list, recently reformatted my home partition from XFS to RAID1 btrfs. I used the default options to mkfs.btrfs except for enabling raid1 for data as well as metadata. Filesystem is made up of two 1TB drives. mike@mercury (0) pts/3 ~ $ sudo btrfs filesystem show Label: none uuid: f08a8896-e03e-4064-9b94-9342fb547e47 Total devices 2 FS bytes used 888.06GB devid 1 size 931.51GB used

Welcome, I''ve been using btrfs for over a 3 months to store my personal data on my NAS server. Almost all interactions with files on the server are done using unison synchronizer. After another use of bedup (https://github.com/g2p/bedup) on my btrfs volume I experienced huge perfomance loss with synchronization. It now takes over 3 hours what have taken only 15 minutes! File

Hi list, I am using kernel 3.9.0, btrfs-progs 0.20-rc1-253-g7854c8b.

Hello, I have a filesystem that has become unusable because of a balance I can''t stop. It is very close to full, and the balance is preventing me from growing it. It was started like this: sudo btrfs filesystem balance start -v -musage=60 -dusage=60 /srv/backups It has been stuck at 0% across reboots and kernel upgrades (currently on 3.8.1), and cancelling it had no effect: Balance

Hello all. What we have: SL6 - kernel 2.6.32-131.2.1.el6.x86_64 btrfs on mdadm RAID5 with 8 HDD - 27T partition.

If we''ve abandoned the idea of putting the number of redundant blocks into the top bits of the type bitmask (and I hope we have), then we''re fairly much there.

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.

Hi, I''m hitting this issue - sda5 is a normal device, nothing to do with loop, encryption etc. # mkfs.btrfs /dev/sda5 WARNING! - Btrfs v0.19-35-g1b444cd-dirty IS EXPERIMENTAL WARNING! - see http://btrfs.wiki.kernel.org before using error checking /dev/sda5 mount status Is there something I can do to resolve this?

Hello, few days ago I returned from FreeBSD where I was using ZFS/GPT disks in raid-1 array back to (Arch)Linux and installed syslinux as bootloader for booting from single MBR disk. Now, after I finished with migration of my /home data, I'd like to deploy both of my 1TB disks using ext4 (btrfs is not stable enough) under LVM2 using raid-1 array & GPT by having all my partitions (/boot,

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

Hi everybody, I am using btrfs as my main fs for some time now, but I am experiencing severe performance drawbacks. I can''t qualify the circumstances, but sometimes during disc access the whole system freezes for some time. Maybe somebody could suggest some general things I could try to search for the problem? Thanks in advance, Florian --- Some background information: $ mount |

Hello all We are experimenting with btrfs and we''ve run into some problems. We are running on two Sun Storage J4400 Arrays containing a total of 48 1 TB disks.

Hallo, linux-btrfs, First I create an array of 2 disks with mkfs.btrfs -d raid0 -m raid1 /dev/sdb1 /dev/sdd1 and mount it at /srv/MM. Then I fill it with about 1,6 TByte. And then I add /dev/sde1 via btrfs device add /dev/sde1 /srv/MM btrfs filesystem balance /srv/MM (it run about 20 hours) Then I work on it, copy some new files, delete some old files - all works well. Only df

Heyho! (This is using btrfs from Debian''s 2.6.32 2.6.32-3-kirkwood kernel (-9 package; btrfs tools is v0.19-16-g075587c) A few observations about btrfsck: a btrfsck run on a 2T volume (4 disks) on a QNAP appliance (512M ram) got killed by Mr. OOM Killer. Initially, I was quite surprised. I''m only moderately surprised now since it might well be that I forgot to enable

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%.
