<p>Dear List,<br /><br />I'm trying out LVM over DRBD and primarly it works.<br />But when i try to force a hardware failure of the first node ( power off ) heartbeat want's to switch over the second storage node, so that goes good.<br />The only bad thing is that i get the error " Device is held open by someone "</p>
<p>I've stopped the iscsi ( ietd ) manualy but that didn't help.<br />So i'm thinking there is something still holding it open, my best quess is lvm.</p>
<p>My current setup:</p>
<p>sdb1 -> drbd0 -> pv -> vg -> lv's</p>
<p>Does anyone have a tought about it what it could be ?</p>
<p>Thanks alot !</p>
<p> </p>
<p>With kindest regards,</p>
<p>Richard.</p>
