Hello again, Thanks for your help. I have upgrade all host but not resolve my errors. - Can't direct migrate VM to reinstaled host. In no case can I migrate VMs from nodes 50 and 52 to the full reinstalled node 51. To move MV to this node 51 I have to power cycle it. Once VM is running I can move it to nodes 50 or 52 but it cannot return to this node 51. - Can't use NOVNC Console on node51. - To put the node in UP from Maintenance, I have to reinstall the host and deselect reboot. If I try to activate it directly it gives me this error: "Cannot activate Host. Host has no unique id." - Another error is that node 51 cannot host the hosted-engine even though I set it as engine as deploy. Does anyone have any idea why? thank you. Please I'm very frustrated. 3 nodes cluster hosted engine over glusterfs
