Please answer these questions before submitting your issue. Thanks!

1. Minimal reproduce step (Required)

1. deploy with 3pd(tc-pd0, tc-pd1, tc-pd2), 2tidb, 3tikv
2. set global tidb_enable_dist_task = 1;
3. scale-out pd to 6 replicas, add (tc-pd3, tc-pd4, tc-pd5)
4. using pd-ctl to delete the tc-pd0, tc-pd1, tc-pd2
5. do add index

2. What did you expect to see? (Required)

add index should success

3. What did you see instead (Required)

add index failed with get member failed
