<p>I got a backup running at this moment, scping /gluster/ovirt/d44ee4b0-8d36-467a-9610-c682a618b698/images/ to a third device.</p>
<p>So, once done, i'll give a shot on the node2 which is running only VDSM as Host agent.</p>
<p>Hope all will be fine !</p>

<p>Hi,</p>
<p>My backups are done, i'm now processing the installation for having the engine in a VM but i got the following error at the first step:</p>
<p>[root@devnix-virt-master02 ~]# hosted-engine --deploy<br />[ INFO ] Stage: Initializing<br />[ INFO ] Generating a temporary VNC password.<br />[ INFO ] Stage: Environment setup<br /> Continuing will configure this host for serving as hypervisor and create a VM where you have to install oVirt Engine afterwards.<br /> Are you sure you want to continue?

<p> </p>
<p>There is no VM running at this moment on this hypervisor (node 2). The error suggests that the storage is still in use.</p>
<p> </p>
<p>[root@devnix-virt-master02 ~]# vdsClient -s 0 getConnectedStoragePoolsList<br />0ae7120a-430d-4534-9a7e-59c53fb2e804</p>
<p> </p>
<p> </p>
<p>Does that mean i must set this hypervisor (node 2) in MAINTENANCE in order to continue the steps described in</p>
<p> </p>
