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

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? Regards, Hans-Kristian -- To

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''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

I came across the tidbit that ZFS has a contract guarantee that the data read back will either be correct (the checksum computed over the data read from the disk matches the checksum stored on disk), or you get an I/O error. Obviously, this greatly reduces the probability that the data is invalid. (Particularly when taken in combination with the disk firmware''s own ECC and checksumming.)

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

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

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 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

Hello, We are using btrfs filesystems in our infrastructure and, at some point of time, they start refusing to create new subvolumes. Each file system is being quota initialized immediately after its creation (with "btrfs quota enable") and then all subfolders under the root directory are created as subvolumes (btrfs subvolume create). Over time, these subvolumes may also be

Hello list, i know what btrfs don''t support swap files. I read arch wiki and when i reading about systemd addon for auto create swapfile on btrfs, i invent the way, how create and using swap file, just see following sh code: swapfile=$(losetup -f) #free loop device truncate -s 8G /swap #create 8G sparse swap file losetup $swapfile /swap #mount file to loop mkswap $swapfile swapon

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

I have been experimenting exporting btrfs subvolumes over nfs. Main subvolume is filesys1 mounted at /filesys1. Below this is subvolume base, user1 is in base and documents is in user1. documents is mounted at /documents. /etc/exports is: /filesys1/base/user1 172.16.0.0/24(rw,no_acl,no_root_squash,fsid=0) /filesys1/user1-snapshot 172.16.0.0/24(rw,no_acl,no_root_squash,fsid=0)

Hi, I reported a bug to anaconda (rhbz 901905), but it might be btfs related.

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! Today I downgraded from Ubuntu''s APT repo "oneiric-proposed" (which brings some kernel 3.0.0-13) back to the standard repo "oneiric". Now I''m not able to mount my btrfs / and /home (both on the same partition) anymore: device fsid SOME-UUID devid 1 transid 84229 /dev/dm-0 parent transid verify failed on 77078528 wanted 83774 found 84226

Hi, I have added 2x2Tb to my existing 2x2Tb raid 1 btrfs filesystem and then ran a balance: # btrfs filesystem show Total devices 4 FS bytes used 1.74TB devid 3 size 1.82TB used 0.00 path /dev/sdd devid 4 size 1.82TB used 0.00 path /dev/sde devid 2 size 1.82TB used 1.75TB path /dev/sdc devid 1 size 1.82TB used 1.75TB path /dev/sdb # btrfs

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]
