I got a backup running at this moment, scping
/gluster/ovirt/d44ee4b0-8d36-467a-9610-c682a618b698/images/ to a third
device. 

So, once done, i'll give a shot on the node2 which is running only VDSM
as Host agent. 

Hope all will be fine ! 

Hi, 

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: 

Ok i put the node2 in maintenance and it continues but i got a new
error: 

root at devnix-virt-master02 ~]# hosted-engine --deploy

Continuing will configure this host for serving as hypervisor and create
a VM where you have to install oVirt Engine afterwards.
Are you sure you want to continue? (Yes, No)[Yes]:

I don't understand what is it expecting for the PATH ? i've no idea what

Could you please give me a clue ? 

Thanks
