<div><span style="font-family: arial, helvetica,sans-serif; font-size: 10pt; color: #000000;">Hi,<br /><br />I had an electrical failure on the server hosting the engine.<br />After the reboot it was able to gain access to it again, log into the GUI, but the currently online node is not leaving "not responsive" status.<br />Of course, the network storage paths are still mounted, the VMs are running, but I can't gain control again.<br /><br />In vdsmd.log, I have a lot of messages like this one :<br />2018-03-27 12:03:11,281+0200 INFO (vmrecovery) [vds] recovery: waiting for storage pool
