<br>
We need to update/reboot the NFS server on wich the hosted engine is installed. This server also hosts a couple of extra storage domains (ISO, Export and a iScsi domain). I'm wondering if this procedure is complete for an oVirt 4.0 installation :<br>
<br>
1-set the environment to global maintenance<br>
<br>
2-set the extra domains to maintenance mode<br>
<br>
3-shutdown the hosted engine<br>
<br>
4-update/reboot the storage server<br>
<br>
5-reboot the hosted engine<br>
<br>
6-reactivate extra domains<br>
<br>
7-disable global maintenance mode<br>
<br>
I'm wondering what's happening after step 4 and how ovirt will react when the NFS storage disapear and come back.<br>
