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

When data in a file is overwritten, starting somewhere in the middle of the file, the overwritten space is counted twice against the space usage numbers. Is this a bug, or did I something wrong? This is what I did: I create a subvolume and limit it to 4 MB, and create a 1000 KB file in the subvol: # btrfs subvol create s Create subvolume ''./s'' # btrfs

The following series implement a way to generate the help messages and the btrfs man page from the sources comments for the "btrfs" commanda . The syntax and the detailed help of every subcommand are stored in the comments before the function which implements the subcommand. The fact that the help messages and the man page are generated from the same source should help to avoid

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!

This idea is from ext4. By this patch, we can make the dio write parallel, and improve the performance. We needn''t worry about the race between dio write and truncate, because the truncate need wait untill all the dio write end. And we also needn''t worry about the race between dio write and punch hole, because we have extent lock to protect our operation. I ran fio to test the

Hi All, the following patches implement the recursively snapshotting and deleting of a subvolume. To snapshot recursively you must pass the -R switch: # btrfs subvolume create sub1 Create subvolume ''./sub1'' # btrfs subvolume create sub1/sub2 Create subvolume ''sub1/sub2'' # btrfs subvolume snapshot -R sub1 sub1-snap Create a snapshot of

Here are 3 patches to avoid undesired aborts of mkfs.btrfs. These are based on top of Chris''s btrfs-progs.git: git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git Thanks, H.Seto Hidetoshi Seto (3): btrfs-progs: error if device for mkfs is too small btrfs-progs: error if device have no space to make primary chunks btrfs-progs: calculate available

Btrfs had some issues with fsync()''ing directories and fsync()''ing after renames. These three new tests cover the 3 different issues we were seeing. This breaks out the dmflakey stuff into a common helper to be shared between generic/311 and generic/321.

I create a new btrfs filesystem and then add a new device and delete the original device. When I run ''btrfs filesystem show'', the total device is two and there is an error that some devices are missing. I also tried to resize the filesystem but didn''t work. Resizing without device id have an error that there is no such device. When the device id is explicitly pass, an

Currently the resize command is under filesystem, and takes a path to the mounted filesystem. This seems wrong to me. Shouldn''t it be under device, and take a path to a device to resize? Otherwise, how can a resize operation when you have multiple devices make any sense? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to

Fedora provides yum-fs-snapshot. If installed, on each package installation or update a snapshot of all btrfs filesystems is taken, so it is possible to revert the installation/update. Suppose an update failed and I want to get back: with # btrfs subvolume set-default yum-snapshot-whatever / I define which snapshot to use at the next boot. After rebooting I decide I really want to stay with

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

I''m trying to use this feature of qgroup: btrfs qgroup assign <srcid> <destid> <path> Assigns the lower level qgroup src to the higher level qgroup dest in the btrfs found in <path>. It is used to build qgroup hierarchies. However, I fail to understand how this feature should work, and I''m getting "ERROR: bad relation requested":

I have Rsync working ok, backing up some server directories onto another server each evening. If I do an rsync back up of a directory - called "test", for example - and in the "test" directory there is a file called "testfile", it gets backed up OK. However, if that file, "testfile" gets deleted from the original "test" directory, when I run

Hi - I'm trying to verify if OpenSSH/SFTP will in fact lock files with advisory file locking in Linux. I can test locking with the linux "flock" command to verify that file locking does work - but when I upload or download a file with SFTP it will not detect a lock. I'm asking about Linux specifically because about a year ago I was doing a similar process in Solaris 9 and
