Hi there, I am newbie and recently started using btrfs. Now facing a weird problem. FWIW, I am on archlinux, kenel v3.8.0, having Btrfs v0.20-rc1. After an abnormal reboot, getting these errors while boot: systemd.fsck[289]: checking extents systemd.fsck[289]: checking fs roots systemd.fsck[289]: checking root refs systemd.fsck[289]: found 23728128 bytes used err is 0 systemd.fsck[289]: total

Hi All, I''m trying to repair a broken fs using btrfsck and am hitting a failed assertion. I''d appreciate any suggestions for what to do next. Is there any thing I can do to help fix this bug? Any other information from my FS which would help? If the FS could be salvaged that would be a bonus, but I''m more interested in providing a useful bug report before wiping the

Hello I think, I somewhat destroyed my btrfs filesystem on my Ubuntu 13.04 kernel 3.8.0-25-lowlatency system. It got destroyed, because the system was hanging for some other reason and I had to remove power... When I try to mount my filesystem (there''s only one, with a few subfilesystems), the system crashes. Also btrfsck dies; always like this: a@ask-home:~$ sudo

Hi, I thought that I would attempt a quick little patch that will make btrfsck into a No-op when called as fsck.btrfsck. The reasoning is that the FAQ states that it is recommended and safe to do so, and the current 12.04 version of Ubuntu just symlinks fsck.btrfsck to btrfsck instead of /bin/true. PS - Apologies if I mess this git send-email up! Dan McGrath (1): btrfs-progs: No-op when

Hi devs, I can''t mount my btrfs-based external disk. I don''t know what happened to the disk, but usually it gets disconnected (usb cable pulled out) buy my 8 months old daughter. Here''s the output from dmesg: [ 299.699543] parent transid verify failed on 528952573952 wanted 22726 found 22728 [ 299.700947] btrfs read error corrected: ino 1 off 528952573952 (dev

NOTE: in order to apply this patch you should: git mv btrfsck.c cmd-fsck.c This patch moves btrfsck in to "btrfs fsck". It also adds support for symlinks to the btrfs binary to retain compablity, =) I think something should be done to the help description but i''m not sure what... Anyway, feedback is welcome. -- To unsubscribe from this list: send the line "unsubscribe

Hi folks! Been using btrfs for quite a while now, worked great until now. Got power-loss on my machine and now i have the "parent transid verify failed on X wanted X found X" problem. So I can''t get it to mount. My btrfs is spread over sda (2tb), sdc(2tb), sdd(1tb). Is this something that an offline fsck could fix ? If so is the fsck-util being developed ? Is there a way to

Dear list members, In my previous thread at http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg23333.html there was a space_cache kernel bug/panic on kernel 3.8. I could successfully "fix" that with rebuilding the cache. But some files were missing/corrupted. So I booted a rescue CD with kernel 3.7 and ran btrfsck --repair, which repaired quite a few things. After a reboot I

I''ve just pushed out a new integration branch to my git repo. This is purely bugfix patches -- there are no new features in this issue of the integration branch. I''ve got a stack of about a dozen more patches with new features in them still to go. I''ll be working on those tomorrow. As always, there''s minimal testing involved here, but it does at least compile on

Is it expected that running btrfsck more than once will keep reporting errors?

A few months ago, my btrfs storage array became corrupted because of a power failure. A while ago, I made this thread to try and resolve the problem. (http://www.digipedia.pl/usenet/thread/11904/15955/) You can find detailed information about the problem in the previous thread, but I am happy to provide any other details. It didn''t really go anywhere in the way of solving my problem. The

Hello, We are using btrfs filesystems in our infrastructure and, at some point of time, they start refusing to create new subvolumes. Each file system is being quota initialized immediately after its creation (with "btrfs quota enable") and then all subfolders under the root directory are created as subvolumes (btrfs subvolume create). Over time, these subvolumes may also be

I have accidently damaged the first block(s) of a btrfs partition and can''t mount it anymore. I can see that my data is still intact by running a command like: cat /dev/sda5 | hexdump -C | more Do any (experimental) tools exist which would allow me to recover the files?

Hi, I use btrfs for my /home drive. It''s a separate drive with just a single partition. I upgraded to ubuntu 13.10 (beta) a few weeks ago, without any real trouble. But I did have too many issues (not with the drive or btrfs, though) so I decided to do a fresh install. The new install failed a few times, so I made another startup usb drive with another program and that one worked fine.

So I''m having a bit of trouble with one of my btrfs filesystems. It isn''t mounting after a power failure. I can''t get restore or btrfsck to run, even on backup supers. I''ve pasted some output below. My btrfs-progs below come from git this morning, running on linux 3.2.0. # mount /dev/md2 /media/test/ mount: wrong fs type, bad option, bad superblock on
