...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 my system(*).

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

Good afternoon btrfs, I have been having issues with snapshots not reading the whole file tree below them. I have installed new btrfs-progs from git://git.darksatanic.net/repo/btrfs-progs-unstable.git made and installed them. My tree is: /Btrfs | |__ nfs1 | |__ data | |__ sites |...

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

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"

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

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

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.)

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

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.

Hello list, i know what btrfs don''t support swap files.
