12.3.7. 调试部分迁移失败
您可以使用 Velero CLI 检查 Restore 自定义资源（CR）日志来调试部分迁移失败警告消息。
当 Velero 遇到没有导致迁移失败的问题时，会导致迁移部分失败。例如，缺少自定义资源定义（CRD），或者源集群和目标集群的 CRD 版本之间存在冲突，则迁移会完成，但不会在目标集群上创建 CR。
Velero 将问题作为部分失败记录，然后处理 备份 CR 中的其他对象。
流程
检查
MigMigrationCR 的状态：$ oc get migmigration <migmigration> -o yaml
输出示例
status: conditions: - category: Warn durable: true lastTransitionTime: "2021-01-26T20:48:40Z" message: 'Final Restore openshift-migration/ccc7c2d0-6017-11eb-afab-85d0007f5a19-x4lbf: partially failed on destination cluster' status: "True" type: VeleroFinalRestorePartiallyFailed - category: Advisory durable: true lastTransitionTime: "2021-01-26T20:48:42Z" message: The migration has completed with warnings, please look at `Warn` conditions. reason: Completed status: "True" type: SucceededWithWarnings使用 Velero
describe命令检查RestoreCR 的状态：$ oc -n {namespace} exec deployment/velero -c velero -- ./velero \ restore describe <restore>输出示例
Phase: PartiallyFailed (run 'velero restore logs ccc7c2d0-6017-11eb-afab-85d0007f5a19-x4lbf' for more information) Errors: Velero: <none> Cluster: <none> Namespaces: migration-example: error restoring example.com/migration-example/migration-example: the server could not find the requested resource使用 Velero
logs命令检查RestoreCR 日志：$ oc -n {namespace} exec deployment/velero -c velero -- ./velero \ restore logs <restore>输出示例
time="2021-01-26T20:48:37Z" level=info msg="Attempting to restore migration-example: migration-example" logSource="pkg/restore/restore.go:1107" restore=openshift-migration/ccc7c2d0-6017-11eb-afab-85d0007f5a19-x4lbf time="2021-01-26T20:48:37Z" level=info msg="error restoring migration-example: the server could not find the requested resource" logSource="pkg/restore/restore.go:1170" restore=openshift-migration/ccc7c2d0-6017-11eb-afab-85d0007f5a19-x4lbf
RestoreCR 会记录日志错误消息，the server could not find the requested resource，代表迁移部分失败的原因。
