Hi Gui,
I'm getting back at this a bit late, but I could now run `btrfsck
--repair` with btrfs-progs 24cf4d8c3ee924b474f68514e0167cc2e602a48d on
Linux 3.16-rc5 in an Oracle VirtualBox VM with Ubuntu 14.04. It doesn't
suceed yet, but at least I'm not getting immediate errors.
Best regards,
Karl

Hi together,
I'm experiencing the following issues when I invoke `btrfsck` on a
sparse file image with a GPT and one (the only) btrfs partition attached
to a loop device

Hi,
There are some patches for fsck flighting, they are integrated in David's
branches.
You can pull from David's latest branch, and see if it helps:
https://github.com/kdave/btrfs-progs integration-20140704
Have a try and see if it helps anyway.
Thanks,

Hi together,

Thanks for the replies, I think that's most of the questions answered.
I'll not bother backing up any VMs, as they won't contain anything worth
backing up. Can anybody answer the last couple of remaining questions?
