similar to: is space really freed after deleting large subvolume?

I was looking through some of the archives and notice a patch submitted to implement: btrfs subvolume show <path-to-subvolume> command. I also noticed that is does not appear to be in the git. This looks like a useful capability. I was trying to find out what the UUID was for a newly created subvolume and have not found out how to do that. Gene -- To unsubscribe from this

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Is it ( yet? ) possible to manipulate the allocation policy on a subvolume level instead of the fs level? For example, to make / use raid1, and /home use raid0?

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)

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

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.

Is there a way to mix RAID 1 and 0 in different subvolumes? I am a new user to btrfs and would like to protect the important files with mirroring, but have a bulk area that is striped for speed and size. For example I want / and /home to be mirrored, but /media can just be striped as it is all data I can easily recreate. I see an item in the Project_ideas wiki entry called "Online raid

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]

Just compiled a custom kernel, but unable to mount a btrfs partition. It essentially says ''unrecognized filesystem''. What could be missing? # File systems # CONFIG_EXT2_FS=y CONFIG_EXT2_FS_XATTR=y CONFIG_EXT2_FS_POSIX_ACL=y CONFIG_EXT2_FS_SECURITY=y # CONFIG_EXT2_FS_XIP is not set CONFIG_EXT3_FS=y CONFIG_EXT3_DEFAULTS_TO_ORDERED=y CONFIG_EXT3_FS_XATTR=y

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

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".

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 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 thought I would try btrfs on a new installation of f14. yes, I know its experimental but stable so it seemed to be a good time to try it. I am not sure if I have missed something out of all my searching but am I correct in thinking that currently: I. it is not possible to boot from a snapshot of the operating system and, in particular, the yum snapshots cannot be used for

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"
