One way this can happen is if one starts the hb manually and then
force<br>
formats on that volume. The format will generate a new uuid. Once
that<br>
happens, the hb tool cannot map the region to the device and thus
fail<br>
to stop it. Right now the easiest option on this box is resetting
it.<br>

Yes, i did reformat it(even more than once i think, last week).
This is a pre-production system and i'm trying various options
before moving into real life.<br>

Did you reformat the volume recently? or, when did you format
last?<br>
