Hello everyone, Btrfs v0.10 is now available for download from: http://oss.oracle.com/projects/btrfs/ Btrfs is still in an early alpha state, and the disk format is not finalized. v0.10 introduces a new disk format, and is not compatible with v0.9. The core of this release is explicit back references for all metadata blocks, data extents, and directory items. These are a crucial building

Various people have said they are going to UKUUG and I wanted to remind people if they are about and want to discuss puppet, facter, etc they can come along. Entry is not restricted to UKUUG attendees, I''ll try and make myself obvious by having some puppet related paraphenalia. http://www.ukuug.org/events/spring2009/social/ Paul --~--~---------~--~----~------------~-------~--~----~

sorry, let me reword my question I would like to be able to time sync the image to the video (using CMML) is there any software that can do that (web-based)? and are there any web-based player that can play the video on left side and display the images on the right side (no flash)? tom_a_sparks --- On Sun, 6/12/09, Tom Sparks <tom_a_sparks at yahoo.com.au> wrote: > I have a theora video

try_to_writeback_inodes_sb_nr returns 1 if writeback is already underway, which is completely fraking useless for us as we need to make sure pages are actually written before we go and check if there are ordered extents. So replace this with an open coding of try_to_writeback_inodes_sb_nr minus the writeback underway check so that we are sure to actually have flushed some dirty pages out and will

Hi Chris. I think it is needed to call mark_inode_dirty() when file size expands in order to flush metadata updates to HDD through sync() syscall or background_writeout(). Thanks.

Hi. I got following BUG trace. This is violation of BUG_ON(!buffer_locked(bh)) check on submit_bh() function. In write_dev_supers(), if wait parameter is set and buffer_uptodate() check is negative, submit_bh() is executed and hit above BUG_ON. So I fixed this issue. Thanks.

Hello everyone, I've just tagged and released Btrfs v0.9. Special thanks to Yan Zheng and Josef Bacik for their work. This release includes a number of disk format changes from v0.8 and also a small change from recent btrfs-unstable HG trees. So, if you have existing Btrfs filesystems, you will need to backup, reformat and restore to try out v0.9. You can find download links and other

Hello everybody, I prepared a kernel patch and an ebuild for btrfs, Fran?ois was kind enough to add btrfs support to his live cd. So Systemrescue CD 0.4.4-beta6 is the first live cd with btrfs-0.11 support (I think). http://www.sysresccd.org/Beta-x86 I will try to keep Fran?ois up to date if decides to keep btrfs support. Have fun! ;) -- Regards, Chris -------------- next part

Hi everyone, The master branch of the btrfs unstable tree: git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable.git master Has a collection of btrfs bug fixes. The three most important fixes here address crashes in the btrfs O_DIRECT code, add a migrate_page operation to avoid metadata corruption as btree pages go through migration, and fix up our NFS support. Otherwise we have

Hi, I try to format a USB memory with a Btrfs. I can format it with mkfs.btrfs without problems. But; when I try to mount it, it fails to mount with the below error messages. But the USB memory works fine with other filesystems (ext4, XFS etc.). So, the hardware is not faulty. tarkane@tarkane:~$ sudo mkfs.btrfs -d single -n 4096 /dev/sdb1 WARNING! - Btrfs v0.18-26-g0030f1d IS EXPERIMENTAL

From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> The pdflush thread is long gone, so this patch removes references to pdflush from btrfs comments. Cc: Chris Mason <chris.mason@fusionio.com> Cc: linux-btrfs@vger.kernel.org Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> --- I expect this patch to be merged via Al Viro''s VFS tree.

V2 -> V3: set ''err'' to -ENOMEM when kmalloc() fails. Thanks to Tao. V1 -> V2: Move kmalloc() before mutex_lock(), suggested by Arjan. file_remove_suid() should be called with i_mutex held, file_update_time() too. So move them after mutex_lock(). Plus, check the return value of kmalloc(). Signed-off-by: WANG Cong <amwang@redhat.com> Cc: Arjan

While testing with my buffer read fio jobs[1], I find that btrfs does not perform well enough. Here is a scenario in fio jobs: We have 4 threads, "t1 t2 t3 t4", starting to buffer read a same file, and all of them will race on add_to_page_cache_lru(), and if one thread successfully puts its page into the page cache, it takes the responsibility to read the page''s data. And

Hi. In btrfs, fdatasync and fsync are identical. I think fdatasync should skip committing transaction when inode->i_state is set just I_DIRTY_SYNC and this indicates only atime or/and mtime updates. Following patch improves fdatasync throughput. #sysbench --num-threads=16 --max-requests=10000 --test=fileio --file-block-size=4K --file-total-size=16G --file-test-mode=rndwr

Hello everyone, As Linus discovered, the new btrfs disk format in 2.6.31-git can be problematic if your FS gets forward rolled to the new format and you end up bisecting back to the old code. It would also be nice to have a way to run btrfsck on a root filesystem and do other assorted tasks. So, I''m making live boot usb images for both x86 and x86-64. They should have enough to get
