When using "-U" option with btrfs-corrupt-block, it will cause a segfault due to a missing break in getopt switch.

- Add incompat flag, otherwise btrfs-progs will report error when operating on btrfs filesystems mounted with lzo option. - Allow to turn on lzo compression for defrag operation: # btrfs filesystem defragment -c[zlib, lzo] <file> Note: "-c zlib" will fail, because that''s how getopt() works for optional arguments.

From: Wade Cline <clinew@linux.vnet.ibm.com> The kernel uses unsigned long long for u64, but PPC64 uses unsigned long by default. This results in print warnings such as: print-tree.c:333: warning: format ‘%llu’ expects type ‘long long unsigned int’, but argument 4 has type ‘u64’ Defining __KERNEL__ before the file <asm/types.h>, or any file that includes this file, will let PPC64

I hit a problem that i can not start scrub when i am trying to track superblock generation mismatch problems. The fact is that we are trying to check whether we have started a scrub operation in userspace, this will make us can''t start scrub if that record file is damaged itself. By adding a option to skip that check, everything will be fine. Signed-off-by: Wang Shilong

After a reorganisation of patches, and sending a bunch of them to Chris, I''ve also updated the integration branch to match that. It''s available from: http://git.darksatanic.net/repo/btrfs-progs-unstable.git/ integration-20110630 The shortlog of 17 patches in this branch beyond the ones I''ve sent to Chris is below. Hugo.

The kernel patch series just sent (Subject: "Btrfs: scrub: print path to corrupted files and trigger nodatasum fixup") introduces two new ioctls to do in-kernel filesystem path construction. This series provides the corresponding userspace changes, adding two new commands to the btrfs utility: -- btrfs resolve inode [-v] <inode> <path> resolves an <inode> to all

This is the next patch series for scrub userland tools. Change log v1->v2: - commands now reachable as "btrfs scrub ..." instead of "btrfs filesystem scrub ..." - ability to scrub a single device instead of a whole file system - superfluous command line options removed - resume is now a separate command ("scrub resume") instead of "scrub start -r" -

The btrfs tool is changed in order to support command line parameters to configure the IO priority of the scrub tasks. Also the default is changed. The default IO priority for scrub is the idle class now. Some basic performance measurements have been done with the goal to measure which IO priority for scrub gives the best overall disk data throughput. The kernel was configured to use the CFQ IO

Ok, I managed to compile the Ogg and Vorbis libs. Then, after modifying the file audio_out.c as follows: original: #include <dlfcn.h> modified: #include <win32/include/dlfcn.h> I was able to (finally!) compile libao. Then I tried to compile the module vorbis-tools, but uninvited problems came to my party. [...] > /usr/bin/ld: multiple definitions of symbol _getopt >

Dear all, I've only just joined this list, but I can't find any mention of this idea anywhere else, so I thought I'd just post here before getting too deep into programming and possibly reinventing the wheel. Here at Aber, we have around 30 unix and linux servers doing core services. Each one is maintaining its own logfiles and, for various reasons, we want to keep these on the

Here''s a simple patch to replace "gcc" with "$(CC)" and "make" with "$(MAKE)". This is required, for example, for Gentoo Linux ebuilds, and it also eliminates a "jobserver unavailable" warning (make-related). -Joe

Hello, I''m using kernel 3.1.0 and I have both / and /home as btrfs. I used suspend to ram quite often and never had a problem, but yesterday I''ve suspended to get into a plane and when I resumed my /home was all about input/output errors. Reboot did not help either. My root (/) did not suffer any problems. Today I''ve upgraded btrfs-progs to latest GIT and tried scrub

Hi everyone, I''ve updated the master branch with the pending stable btrfs-progs commit that should make the 0.20 release. Thanks to Hugh for helping to queue up a few of them. We''ll have more frequent releases from here as we pull in the major new features going into progs (raid5/6, send/receive, quotas, fsck improvements). Please give it a shot and let me know if you see any

Hi Chris, this serie of patches updated the command "btrfs filesystem df". I update this command because it is not so easy to get the information about the disk usage from the command "fi df" and "fi show". This patch was the result of some discussions on the btrfs mailing list. Many thanks to all the contributors. From the man page (see 2nd patch): [...] The
