> It's seem you setup two difference loopback devices on the same image > file. Please try mount the image file this way. I think btrfs.ko should have a global list of uuids that are mounted. It could then forbid to mount a superblock with a uuid that is already mounted somewhere else. Maybe it could only perform this check for writable mounts, which I suspect is all mounts today ;). It wouldn't be perfect but it is a trivial amount of code and it would have prevented this honest mistake. - z _______________________________________________ Btrfs-devel mailing list [email protected] http://oss.oracle.com/mailman/listinfo/btrfs-devel
