Hi,

I have two ovirt environments on the same network.

2 switches (10G switch for storage and 1G switch for data / management)

1) Prod environment:
3 oVirt 4.4.6 nodes (1 port 10G per node for storage gluster and 1 port 1G for data / management)

2) Lab environment
2 oVirt nodes 4.4.6 (1 Port 10G per node for storage gluster and 1 port 1G for data / management)

The storage is on the same vlan and subnet for both environments.

When I restart one of my lab servers, I have communication cuts/glitch on my production ovirt clusters. I even had server reboots.

Do you know why ?

Here somes log :


VDSM ovnode1.telecom.lan command SpmStatusVDS failed: Connection timeout for host 'ovnode1.telecom.lan', last response arrived 42479 ms ago.
Host ovnode1.telecom.lan is not responding. It will stay in Connecting state for a grace period of 88 seconds and after that an attempt to fence the host will be issued.
