Reading through the changelog it doesn't really explain what those capabilities are. I've downloaded 2.01.14 and installed it but alas the man pages don't have anything about the -m option either. So, can someone quickly explain (or point me to documentation) what mirror options/capabilites are currently available and what options are planned? I'm most curious about whether the ability to attach one lv to another and form a mirror and then split the mirrored lv into two distinct lvs that are both mountable (similar to a snapshot only a completely separate lv). We use this capability within veritas all the time when moving disk around online and its really the only thing holding us back from scrapping veritas in favor of lvm.
