Okay thanks for the details on btrfs-image. I was about to try with previous version of btrfs-image. I'll use v4.14 (https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.14.tar.xz) and check again. ---- Cheers, Lakshmipathi.G http://www.giis.co.in http://www.webminal.org On Fri, Nov 24, 2017 at 1:36 PM, Qu Wenruo <quwenruo.btrfs@xxxxxxx> wrote: > > > On 2017年11月24日 15:47, Lakshmipathi.G wrote: >> Hi Qu, >> >> I'm using btrfs-progs devel branch. mount command is failing with misc/021. >> When I tried to manually mount it. dmesg shows "unrecognized super >> flag: 17179869184" >> and interestingly "df -h" shows 16E as available! > > That flag is meta dump flag, any image recovered from btrfs-image should > have that flag. > > 16E may also related to that, but not a big problem as btrfs-image > result should only be used by developers, and all its data is wiped out. > (Maybe one day we will not allow RW mount for such image) > > > The problem happens when you try to mount the image, there may be some > new commits doing more restrict check for rw mount in devel branch. > > Would you please try v4.14 kernel? > > Thanks, > Qu > >> >> https://asciinema.org/a/4JGYg7YGQz1PHtdBRJ6AVw0fh >> >> Let me check further. >> ---- >> Cheers, >> Lakshmipathi.G >> http://www.giis.co.in http://www.webminal.org >> >> >> On Fri, Nov 24, 2017 at 9:55 AM, Lakshmipathi.G >> <lakshmipathi.g@xxxxxxxxx> wrote: >>> Hi Qu, >>> >>> I'm using the same instance.
