Error when trying to initialize libovsdb NB client

[paupal1]

Trying to test up ovn-kubernetes locally to do some testing/experimentation. I ran into this and am unsure how to mitigate or continue. Would love any any pointers. db seems to be running on right ports 6641 & 6642.

Hi @paupal1,

Object type nbdb.NBGlobal contains field HvCfgTimestamp (int) ovs tag hv_cfg_timestamp: Column does not exist in schema. Object type nbdb.LogicalRouterPort contains field Ipv6Prefix ([]string) ovs tag ipv6_prefix: Column does not exist in schema Object type nbdb.LogicalRouterStaticRoute contains field BFD (*string) ovs tag bfd: Column does not exist in schema. Mapper Error, etc.

Can you make sure that the version of OVN that you are using matches what ovn-kubernetes expects? Your errors indicate that your version of OVN is older than what ovn-kubernetes would expect, and it does not contain the required fields in its database.

E.g., for fedora, check the Dockerfile for a version of OVN that should work:

[akaris@linux ovn-kubernetes (master)]$ grep 'ARG ovn' ./dist/images/Dockerfile.fedora
ARG ovnver=ovn-21.09.0-3.fc33

Let's e.g. look at the model for LogicalRouterStaticRoute https://github.com/ovn-org/ovn-kubernetes/blob/master/go-controller/pkg/nbdb/logical_router_static_route.go

// LogicalRouterStaticRoute defines an object in Logical_Router_Static_Route table
type LogicalRouterStaticRoute struct {
    UUID        string                          `ovsdb:"_uuid"`
    BFD         *string                         `ovsdb:"bfd"`
    ExternalIDs map[string]string               `ovsdb:"external_ids"`
    IPPrefix    string                          `ovsdb:"ip_prefix"`
    Nexthop     string                          `ovsdb:"nexthop"`
    Options     map[string]string               `ovsdb:"options"`
    OutputPort  *string                         `ovsdb:"output_port"`
    Policy      *LogicalRouterStaticRoutePolicy `ovsdb:"policy"`
}

When you look at the OVN git blame, you can see that the BFD field was only added 10 months ago: https://github.com/ovn-org/ovn/blame/f6aba21c9de8952beccf7ee7e98cfa28618f1edf/ovn-nb.ovsschema#L417

你好@paupal1,

Object type nbdb.NBGlobal contains field HvCfgTimestamp (int) ovs tag hv_cfg_timestamp: Column does not exist in schema. Object type nbdb.LogicalRouterPort contains field Ipv6Prefix ([]string) ovs tag ipv6_prefix: Column does not exist in schema Object type nbdb.LogicalRouterStaticRoute contains field BFD (*string) ovs tag bfd: Column does not exist in schema. Mapper Error， ETC。

你能确保你使用的 OVN 版本与 ovn-kubernetes 期望的相匹配吗？您的错误表明您的 OVN 版本比 ovn-kubernetes 预期的要旧，并且它的数据库中不包含必填字段。

例如，对于 fedora，检查 Dockerfile 中应该工作的 OVN 版本：

[akaris@linux ovn-kubernetes (master)]$ grep 'ARG ovn' ./dist/images/Dockerfile.fedora
ARG ovnver=ovn-21.09.0-3.fc33

让我们看看 LogicalRouterStaticRoute 的模型 https://github.com/ovn-org/ovn-kubernetes/blob/master/go-controller/pkg/nbdb/logical_router_static_route.go

// LogicalRouterStaticRoute defines an object in Logical_Router_Static_Route table
type LogicalRouterStaticRoute struct {
  UUID        string                          `ovsdb:"_uuid"`
  BFD         *string                         `ovsdb:"bfd"`
  ExternalIDs map[string]string               `ovsdb:"external_ids"`
  IPPrefix    string                          `ovsdb:"ip_prefix"`
  Nexthop     string                          `ovsdb:"nexthop"`
  Options     map[string]string               `ovsdb:"options"`
  OutputPort  *string                         `ovsdb:"output_port"`
  Policy      *LogicalRouterStaticRoutePolicy `ovsdb:"policy"`
}

查看OVN git blame，可以看到BFD字段是10个月前才添加的： https://github.com/ovn-org/ovn/blame/f6aba21c9de8952beccf7ee7e98cfa28618f1edf/ovn-nb.ovsschema#L417
