Hi all, I''m trying to set up traffic shaping and I''m having some difficulty. Here is what I want, and where I am. 1. HTTP and SMTP traffic needs to be priority 1. 2. All other traffic priority 2 3. Torrent traffic priority 3. My distro is Fedora Core 4, and the torrent protocol does not appear in /etc/protocols. The only protocol is TCP, which HTTP and SMTP is built on top

I noticed that btrfs fi defrag -c<method> can''t be used to compress files unless they are fragmented. This patch corrects the problem, by informing should_defrag_range if compression is enabled, and skipping tests for extent and adjacent extents if it is.

Kernel 3.1-rc8 btrfs-progs-0.19 mount options: noatime,autodefrag (space_cache is enabled) There are snapshots present on the filesystem. When I do a btrfs fi defrag on a file, the file becomes much more fragmented. The end result can be a file with 20k times more fragments than before. Initially I thought the extents were just smaller but were next to each other, so I checked with both

Hi all, i am new on btrfs, i am testing KVM on btrfs (host: kernel x86-64 3.5.3), the performance is reasonable. I have two question on defrag, can someone help me? 1. According to btrfs wiki, defragment a COW file will produce two unrelated files. Does it apply to the "autodefrag" mount option? 2. Is there any command for the fragmentation status of a file/dir ? e.g. fragment

Will stephen's defrag run in a ext3 partion correctly? What about the performance? _________________________________________________________ Do You Yahoo!? 摊开你的掌心 让我看看你 http://sweepstakes.yahoo.com/2002cnuser

I noticed a few days ago that btrfs fi defrag -cXXX can not be used to compress files unless they are fragmented. The attached patch passes the compression flag to should_defrag_range, where it disables the adjacent-extent and extent size checks if set. The inline/sparse extent check is not modified - I assumed it would not be useful to compress inline extents. -- Andrew Mahone andrew DOT mahone

Commit 5ac00add added a testnset mutex and code that disallows running administrative tasks in parallel. It is prevented that the device add/delete/balance/replace/resize operations are started in parallel. By mistake, the defragmentation operation was included in the check for mutually exclusiveness as well. This is fixed with this commit. Signed-off-by: Stefan Behrens

We need such a sanity check for wrong start when we defrag a file, otherwise, even with a wrong start that''s larger than file size, we can end up changing not only inode''s force compress flag but also FS''s incompat flags.
