Fwd: btrfs Wiki account request
I wrote a simple alternative for a script that is currently on the
btrfs wiki (for showing quotas) in bash instead of Python. I have
attempted to add this to the page but after entering the captcha 15
times my account was rejected because of a missing bio. Maybe someone
can add this to https://btrfs.wiki.kernel.org/index.php/Quota_support:
#!/bin/bash
[[ ! -d $1 ]] { echo Please pass mountpoint as first argument 2 ;
exit 1 ; }
while read x i x g x x l x p
do
volName[i]=$p
done (btrfs subvolume list $1)
while read g r e
do
[[ -z $name ]] echo -e subvol\tqgroup\ttotal\tunshared
group=${g##*/}
[[ ! -z ${volName[group]} ]] name=${volName[group]} || name='(unknown)'
echo $name $g `numfmt --to=iec $r` `numfmt --to=iec $e`
done (btrfs qgroup show $1 | tail -n+3) | column -t
Thanks,
Sjon

btrfs-progs 0.20rc1.1, linux 3.7.6 - new filesystem: failed to recover relocation
I have just completed installing an archlinux machine with 2 btrfs partitions, one works fine (the rootfs), the other one I cannot mount. Even after recreating the filesystem I still cannot mount it. I receive te following output in my dmesg: [ 6526.037089] device fsid 74cc8eb8-f60a-4797-9ab3-0c8ac4fe847f devid 1 transid 3 /dev/vdb1 [ 6526.037763] btrfs: disk space caching is enabled [ 6526.038415] btrfs: failed to recover relocation [ 6526.039716] btrfs: open_ctree failed this is on a virtual machine using libvirt, a virtio hdd and kvm; btrfsck reports no errors. An image of this filesystem can be found here: http://home.react.nl/~sjon/bug-reports/btrfs/btrfs-failed-to-recover-relocation (29 KiB) After recreating the same filesystem again on a smaller (100Mb) filesystem btrfsck reports: Check tree block failed, want=139264, have=0 Check tree block failed, want=139264, have=0 Check tree block failed, want=139264, have=0 read block failed check_tree_block Couldn't read chunk root and btrfs-image segfaults on this. I have dumped the partition with dd, it can be found here: http://home.react.nl/~sjon/bug-reports/btrfs/vdb1.raw.gz (98 KiB). I couldn't find any recent reports mentioning these sort of problems.

I'll get to adding it to progs integration soon. david While debugging this my vm-host began throwing segfaults as well, so I think this problem was caused by something else (namely this: https://bugzilla.redhat.com/show_bug.cgi?id=893854).

Re: btrfs-progs 0.20rc1.1, linux 3.7.6 - new filesystem: failed to recover relocation
After converting all my raw images to qcow2 the host no longer segfaults, but I still get a corrupted btrfs filesystem. Please have a look at this new image at http://home.react.nl/~sjon/bug-reports/btrfs/btrfs-corrupt.qcow2.gz (16 KiB) It contains a 20 GiB disk with 1 partition that btrfsck (again) has no problems with, but I cannot mount it.
