Hi all. I'm using btrfs for a long time. It's the time for me to report an issue. I use btrfs for my home and I dded the block device to a new computer. It works well. But when I tried to mount both up and do syncing between them, I found the two mountpoints are the same! i.e. when I touch a file on my original partition, the same file appears in the new one now. Vice versa. I wrote a script to replay it (using loop, but result is the same): dd if=/dev/zero of=ori.img bs=16M count=16 mkfs.btrfs ori.img cp ori.img new.img mkdir ori new mount -o loop ori.img ori mount -o loop new.img new touch ori/foo ls new You'll see the file `foo' also appears in the `new' directory. I guess there's something wrong with btrfs in how to deal with two partition with same UUID or something else, but I'm not sure. It's proved on Gentoo with Kernel 3.2.11, as well as Ubuntu with Kernel 3.1.9 Tydus -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
