<div dir="ltr"><div><div><div><div><div><div><div><div><div><div>Hello All,<br><br></div>I'm running my test/dev environments in Mirantis openstack.<br></div>Fuel - 7.0</div><div>openvswitch 2.3.1-1~u14.04+mos2</div><div>3 controllers, 14 compute nodes.<br></div><div><br></div>Recently, many vms lose connectivity completely, and they cannot renew IPs by doing a network restart too. Sometimes a compute node reboot fixes the problem.<br></div>Sometimes, we keep restarting various neutron services like openvswith-agent etc.<br></div>But all these, without understanding the problem.<br><br></div>Can someone guide me where to start troubleshooting?</div><div><br></div>A friend of mine suggested that this version of openvswitch has many bugs and an upgrade might help. Is it even possible to do this on an online cluster?<br><br></div>This issue has become very frequent and also spreads to more nodes. Some pointer to understanding this issue will be of great help.<br><br></div>Thanks and Regards,<br></div>Raja.<br><div><div><div><div><div><div><div><div><div><div><div><div><div><br><br><br clear="all"><div><div><div><br>-- <br><div class="gmail_signature">:^)</div>
