我能够在一个节点（一台物理机）上部署多副本吗，如在一个节点部署 3 个 tidb，3 个 pd，3个 tikv ？
我使用 tidb operator 部署，一共 3 个 pd 只有一个 pod 正常 runnning，另外两个都报了 etcd 的错：
[main.go:288] [“run server failed”] [error=“[PD:etcd:ErrStartEtcd]member 10f0df000a58db81 has already been bootstrapped: member 10f0df000a58db81 has already been bootstrapped”] [stack=“main.start\n\t/workspace/source/pd/cmd/pd-server/main.go:288\nmain.createServerWrapper\n\t/workspace/source/pd/cmd/pd-server/main.go:194\ngithub.com/spf13/cobra.(*Command).execute\n\t/root/go/pkg/mod/github.com/spf13/cobra@v1.8.0/command.go:987\ngithub.com/spf13/cobra.(*Command).ExecuteC\n\t/root/go/pkg/mod/github.com/spf13/cobra@v1.8.0/command.go:1115\ngithub.com/spf13/cobra.(*Command).Execute\n\t/root/go/pkg/mod/github.com/spf13/cobra@v1.8.0/command.go:1039\nmain.main\n\t/workspace/source/pd/cmd/pd-server/main.go:71\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:272”]
使用 operator 部署的话能够配置每个 pd 副本的 initial-cluster-state 吗？
更新：测试集群中有两个节点，我将 pd 的 replica 设置为2，可以看到两个 pd 的 pod 分别被schedule 到两个节点上了，并且分别挂载到各自的 pvc。
但是只有一个 pod 正常运行，另一个 pod 仍然报了相同的错误：
