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 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

In reflink we update the id info in the disk but forget to update the corresponding information in the VFS inode. So update them accordingly in case we want to preserve the attributes.

Hi, I don't know if this is a problem of SLES11 or winbind itself. I recently installed the lastest samba winbind 3..5.2 on a SLES9 box and a SLES11 box. If I remove a user from a group in Active Directory the change is visible immediately on the SLES9 box but not on the SLES11 box. Both are running exactly the same version of winbind: gedaiv64:~ # cat /etc/SuSE-release SUSE Linux

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 built a couple new servers on SLES11 because I needed to use USB. Since SLES11 has xen 3.4 packages that seemed like the way to go. I''m questioning the stability of the two new servers compared to my SLES10SP2 servers. I''m also questioning the performance of Windows domUs. On Thanksgiving day one of my SLES11 servers running 7-8 domUs crashed and restarted three times. Being

Inlined xattr shared free space of inode block with inlined data or data extent record, so the size of the later two should be adjusted when inlined xattr is enabled. See ocfs2_xattr_ibody_init(). But this isn't done well when reflink. For inode with inlined data, its max inlined data size is adjusted in ocfs2_duplicate_inline_data(), no problem. But for inode with data extent record, its

I'm trying to mount a ocfs2 volume (created on sles11) on my sles10sp2 server. I created the volume with these options: "mkfs.ocfs2 -C 128k -L CLUFS -M cluster -N 16 /dev/sdc". (dev/sdc is an iscsi device). It works to mount the volume with "mount.ocfs2 /dev/sdc /ocfs2" on my boxes (with o2cb configured for both nodes). When creating files on the ocfs2 volume I cant see

The 9p-virtio transport does zero copy on things larger than 1024 bytes in size. It accomplishes this by returning the physical addresses of pages to the virtio-pci device. At present, the translation is usually a bit shift. However, that approach produces an invalid page address when we read/write to vmalloc buffers, such as those used for Linux kernle modules. This causes QEMU to die printing:

Dear Team, Maybe somebody already tried to install mpfr and gsl packages for R on SLES. Exactly I try to install Rmpfr_0.6-1.tar.gz and gsl_1.9-10.3.tar.gz on SLES11 SP4. These are the available packages from official SLES SDK media: rtest:/home/ruser # rpm -qa | grep -i gsl gsl-devel-1.11-1.30 gsl-1.11-1.30 rtest:/home/ruser # As I understand gsl is from 1.11 till 1.30 level.

Hi, I run into problems with the ipaddress fact using the latest Facter gem (1.6.4, 1.6.5) on SLES11. The versions and gems I use work perfectly fine on SLES10 SP3. The problem: running "facter" without arguments results in an error, even though the erroring fact "ipaddress" is ok. test:~ # cat /etc/SuSE-release SUSE Linux Enterprise Server 11 (x86_64) VERSION = 11 PATCHLEVEL

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, I am using linux kernle-2.6.15, iptables-1.4 and bridge-utils-1.4. Everything intslled without any issue and i am able to enable the bridge and traffic is also flowing without any issue. But i did not see any traffic on the iptables forward chain due to which i am not able to control the traffic. Do i requie enable anything more to make the traffic pass through iptables forward chain.

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 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.
