Hello All, Mirantis version 7.0 ovs version: 2.3.1-1~u14.04
Some more reading on this points to possible bugs in ovs versions and advise to upgrade the same. Eg: Redhat solution doc 2104871. Can someone put some more light on this? If needed, is there a way for me to upgrade the ovs packages and dependencies alone, while leaving rest of the cluster intact? Any help on this is highly appreciated. Thanks, Raja.
