I think you should be *very* concerned about the situation where 2<br>
guests mount an ext3 partition and start to manipulate files<br>
*sequentially*. It looks like you *are* concerned (rightly), since you<br>
wrote that only one client *mounts* the partition at a time.<br>

What if one starts, e.g., creating files or appending content to<br>
existing files (and allocating new blocks, etc., in the process)? The<br>
other clients won't be aware of it.<br>
<br>
I admit I have not thought long and hard about it, but it sounds<br>
dangerous to me.<br>
