similar to: File cloning across subvolumes with BTRFS_IOC_CLONE ioctl

Glück Auf! I know its been discussed more then ones, but as a user I really would like to see the patch for allowing this in the kernel. Some users tested this patch successfully for weeks or months in 2 or 3 kernel versions since then, true? I''d say by creating a snapshot, it''s nothing else in the end. More then one file or tree sharing the same data on disc, or am I wrong?

It''s been nearly a year since the patches needed to implement a reflinked copy between subvolumes have been posted (http://permalink.gmane.org/gmane.comp.file-systems.btrfs/9865 ) and I still get "Invalid cross-device link" error with Linux 3.2.4 while I try to do a cp --reflink between subvolumes. This is a *very* useful feature to have (think offline file-level

I am testing a Btrfs root file system with Debian (kernel 2.6.32) under KVM. jason@vrtl:~$ touch testfile jason@vrtl:~$ cp --reflink testfile /tmp cp: failed to clone `/tmp/testfile'': Invalid argument This is with GNU Coreutils 8.0 taken from debian Sid. Is this a Coreutils issue, a Btrfs problem or something in my local configuration? All the other issues that I have encountered so

Hi, I''ve some btrfs fs which are encrypted with loopaes. I decrypt them in a script during bootup. Now I want to determine if the decrypted fs is a btrfs fs. If not I missspelled the password and I can handle that error in my script. Thanks for any help!

I''ve been thinking about this for a while, from a perspective of how to make it work by allocating i-node numbers from a global pool, but yesterday I realized that offering the feature would be a bad idea because it violates the semantics of file systems. I will be happy to expand on that point if anyone disagrees with it. dln -- "It is merely a matter of persistence." --

Hi all, Just a quick question but can''t find an obvious answer. Can I create/convert a existing (btrfs) directory into a subvolume? It would be very helpful when transferring ''partitions'' into btrfs. I found a similar question way back in google, but that site is down now generally. Thanks in advance. -- To unsubscribe from this list: send the line

This testscript creates reflinks to files on different subvolumes, overwrites the original files and reflinks, and moves reflinked files between subvolumes. Originally submitted as testcase 302, changes are made based on comments from Eric: http://oss.sgi.com/archives/xfs/2013-03/msg00231.html Two new common/rc functions used in this script (_require_cp_reflink and _verify_reflink) have been

Hello, This is the second attempt to bring in cross subvolume reflinks into btrfs. The first attempt was NAKed due to missing vfs mount checks and a clear description of what btrfs subvolumes are and probably also why cross subvolume reflinks are ok in the case of btrfs. This version of the patch comes from David and is in SUSE kernels since a long time, so it is tested and working. The patch

Hi everyone, I described the reflink operation at the Linux Storage & Filesystems Workshop last month. Originally implemented as an ocfs2-specific ioctl, the consensus was that it should be a syscall from the get-go. Here's some first-cut patches. For people who have not seen reflink, either at LSF or on the ocfs2 wiki, the first patch contains Documentation/filesystems/reflink.txt to

Hi guys, I've got a problem where if I set permissions on a folder(Admin) "setfacl -R -d -m u::rwx,g::wrx,o::- Admin/" and "setfacl -m o:- Admin" I get the following. mail:/data/samba/shared # getfacl Admin/ # file: Admin # owner: BCP+administrator # group: samba user::rwx user:samba:rwx group::rwx group:BCP+admin:r-x mask::rwx other::--- default:user::rwx

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 want to make you aware of a possible bug in the reflink handling of btrfs: When I reflink a file larger 2GB (on the same subvol), the reflinking fails. But it works fine for files smaller 2GB in size. I was able to track this down to btrfs with great support of Martin Raiber who created a small demo code: Source: https://urbackup.atlassian.net/secure/attachment/10201/reflink.cpp Compile: g++
