similar to: btrfs balancing start - and stop?

Hey all, Just did a btrfs balance on a single device. Before the balance operation here is the df result: inglor@tiamat ~$ btrfs fi df /home Data: total=19.19GB, used=9.34GB System, DUP: total=32.00MB, used=4.00KB Metadata, DUP: total=896.00MB, used=227.98MB Then I issues a balance operation relocating the chunks across a single device: inglor@tiamat ~$ sudo btrfs fi balance /home [sudo]

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

Hallo, linux-btrfs, I''m working with btrfs for some days. btrfs-progs-20101101, kernel 2.6.35.8 (both self compiled). First step: mkfs.btrfs /dev/sdd1 mount /dev/sdd1 /srv/MM for a 2 TByte partition, worked well. Copying about 1,5 TByte data to this partition worked well. Second step: btrfs device add /dev/sdc1 /srv/MM btrfs filesystem balance

Hi folks, I''m using Ubuntu 12.10 Quantal with # uname -r 3.5.0-24-generic And it seems I cannot defrag : # filefrag /boot/initrd.img-3.5.0-24-generic /boot/initrd.img-3.5.0-24-generic: 3 extents found # btrfs filesystem defrag /boot/initrd.img-3.5.0-24-generic # echo $? 20 # filefrag /boot/initrd.img-3.5.0-24-generic /boot/initrd.img-3.5.0-24-generic: 3 extents found Any clue

After a reorganisation of patches, and sending a bunch of them to Chris, I''ve also updated the integration branch to match that. It''s available from: http://git.darksatanic.net/repo/btrfs-progs-unstable.git/ integration-20110630 The shortlog of 17 patches in this branch beyond the ones I''ve sent to Chris is below. Hugo.

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

Greetings, until yesterday I was running a btrfs filesystem across two 2.0 TiB disks in RAID1 mode for both metadata and data without any problems. As space was getting short I wanted to extend the filesystem by two additional drives lying around, which both are 1.0 TiB in size. Knowing little about the btrfs RAID implementation I thought I had to switch to RAID10 mode, which I was told is

Hi, how can I do the following in a shell script: - check whether my file system supports cp --reflink? - check whether two files share the same data on disk, i.e. one has been created by cp --reflink of the other?

i am looking at using btrfs for a new project and i have a few questions:     * i have heard that as it currently stands Btrfs has some issues to be used as a Lustre file system; is he aware of the issues and any plans to address these and integrate Btrfs in to Lustre     * any plans to support native clustering on Btrfs     * on ZFS the ZIL is a separate device, any plans to implement a the

I''m wondering is space really freed after deleting large subvolume? Will space be immediately available to other data like other subvolumes? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I''ve just pushed out a new integration branch to my git repo. This is purely bugfix patches -- there are no new features in this issue of the integration branch. I''ve got a stack of about a dozen more patches with new features in them still to go. I''ll be working on those tomorrow. As always, there''s minimal testing involved here, but it does at least compile on

Hi, I wanted to create a new btrfs fs for my backups. When trying to mkfs.btrfs for that device, I''m getting "error checking /dev/loop2 mount status" With strace I see where the problem is: lstat("/dev/disk/by-id/ata-INTEL_SSDSA2M160G2GC_CVPO939201JX160AGN-par", 0x7fffa30b3cf0) = -1 ENOENT (No such file or directory) The problem is there is something missing

Hallo, "never change a running system" ... For some months I run btrfs unter kernel 3.2.5 and 3.2.9, without problems. Yesterday I compiled kernel 3.3.4, and this morning I started the machine with this kernel. There may be some ugly problems. Copying something into the btrfs "directory" worked well for some files, and then I got error messages (I''ve not

Hi What is the general state of btrfs RAID6 as of kernel 3.13-rc1 and the latest btrfs tools? More specifically: - Is it able to correct errors during scrubs? - Is it able to transparently handle disk failures without downtime? - Is it possible to convert btrfs RAID10 to RAID6 without recreating the fs? - Is it possible to add/remove drives to a RAID6 array?

Hi, I''ve observed a rather strange behaviour while trying to mount two identical copies of the same image to different mount points. Each modification to one image is also performed in the second one. Example: dd if=/dev/sda? of=image1 bs=1M cp image1 image2 mount -o loop image1 m1 mount -o loop image2 m2 touch m2/hello ls -la m1 //will now also include a file calles "hello"

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, my btrfs "hangs" when doing a balance operation. I''m using a 3.7.1 kernel from opensuse: linux-opzz 3.7.1-2.10-m4 #11 SMP PREEMPT Fri Jan 11 18:04:04 CET 2013 x86_64 x86_64 x86_64 GNU/Linux and Btrfs v0.19+ I did a scrub which completed without errors. Then I tried "btrfs filesystem balance /" which work fine for the first 23 of 46 chunks, then ist stopped
