I've been seeing this as well. It's new with 3.2, and I haven't yet been able to track it down. The first thing that happens when we mount the FS is a block layer invalidate, and that must be dropping the write. It's also possible (but very unlikely) that mkfs.btrfs is neglecting to write that block. Do you have a reliable way to reproduce? If so, can you try with a much older mkfs.btrfs. -chris -- 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
