Hello,
Yeah you can't mount images, we clear out the chunk tree so nothing works.
Let me know if you run into any problems in the future. Thanks,
That's surprising, I haven't seen it mentioned anywhere.
With any other filesystem I could use an LVM snapshot to save the
original state, but with a multi-device btrfs it would be very risky.
Origin and snapshot volumes could easily get mixed up by kernel and tools.
I tried that in qemu, and I've seen btrfs happily mount 1 origin and 1
snapshot device as a single FS. And then I've seen it mount both origin
devices, even though one of them had old content. Naturally it
complained a lot about bad checksums.
Is there any way to avoid such mix-ups? To somehow mark devices so that
btrfs would know these devices belong together?
Regards
