If the lvm snapshot is visible to btrfs (i.e., btrfs dev scan), it will appear as another device which belongs to the original filesystem with a duplicate devid. This might result in bad things happening, or possibly just hilarity. You have a backup that isn't just an lvm snapshot, right? -- 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
