If you create a subvolume below /mnt/[12] and run the test there, you have the problem reproduced again :) for i in 1 2; do mkdir /mnt/$i truncate -s 4G /mnt/$i.img mkfs.btrfs /mnt/$i.img mount -o loop /mnt/$i.img /mnt/$i done btrfs subv create /mnt/1/sub btrfs subv create /mnt/2/sub mkdir /mnt/1/sub/testdir mkdir /mnt/1/sub/testdir/1/ mkdir /mnt/1/sub/testdir/2/ dd if=/dev/urandom of=/mnt/1/sub/testdir/aa count=16 dd if=/dev/urandom of=/mnt/1/sub/testdir/bb count=16 mkdir /mnt/1/sub/snapshots btrfs sub snap -r /mnt/1/sub/ /mnt/1/sub/snapshots/backup2 btrfs sub snap -r /mnt/1/sub/ /mnt/1/sub/snapshots/backup3 btrfs send /mnt/1/sub/snapshots/backup3/ | btrfs receive /mnt/2/sub/ umount /mnt/[12]; rm /mnt/[12].img; rmdir /mnt/[12] -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
