Hi, The following series of patches implements in btrfs an ioctl to do out-of-band deduplication of file extents. To be clear, this means that the file system is mounted and running, but the dedupe is not done during file writes, but after the fact when some userspace software initiates a dedupe. The primary patch is loosely based off of one sent by Josef Bacik back in January, 2011.

Hi all - The following 9 patches add more error handling to the btrfs code: - Add btrfs_panic - Catch locking failures in {set,clear}_extent_bit - Push up set_extent_bit errors to callers - Push up lock_extent errors to callers - Push up clear_extent_bit errors to callers - Push up unlock_extent errors to callers - Make pin_down_extent return void - Push up btrfs_pin_extent errors to

...packet size. Sent a recent note to the cygwin list (used cygwin in the testing). My experience was to use the cifs protocol as easiest (over a local network). With a 10Gb (limited to 8Gb due to running on older PCIe interface) card, I'm getting: /h> bin/iotest Using bs=16.0M, count=64, iosize=1.0G R:1073741824 bytes (1.0GB) copied, 1.67486 s, 611MB/s W:1073741824 bytes (1.0GB) copied, 4.01592 s, 255MB/s .... Also, on a local net, using Jumbo packets also helps (I have a 9000B MTU on my local net). The speeds / values using 'Bytes', (2**3) use the base2 prefixes for consistenc...

What is the maximum speed for download from a samba share? I have a 100 kbit/s Internet The maximum speed for a download from my  webserver with samba is about 25.000 kbit/s The bottleneck is the samba access.  Without samba  I can download with 100 kbit/s So the question? is it possible to get more speed or is this the maximum speed with samba? I tried a lot of hints for samba tuning but

Hi all - Here''s my current error handling patchset, against 3.1-rc8. Almost all of this patchset is preparing for actual error handling. Before we start in on that work, I''m trying to reduce the surface we need to worry about. It turns out that there is a ton of code that returns an error code but never actually reports an error. The patchset has grown to 65 patches. 46 of them

Hi all, These are new releases of dm-ioband and blkio-cgroup. The major changes of these releases are: - dm-ioband can be configured through the cgroup interface. The bandwidth can be assigned on a per cgroup per block device basis. - The event tracing is supported that helps in debugging and monitoring dm-ioband. - A document for blkio-cgroup is available at
