Summary issue:
Config cluster with 5 SCs.

  • Starting cluster: SC5 is active, SC4 standby and [SC1-SC3] is quiesced. SC1 and SC2 are promoting those nodes to become ACTIVE (by rde component). SC5 is answering the take-over request from SC2 first and reject this request. Then SC5 is rebooted (manually) before answering the request from SC.

  • After SC5 is rebooted. SC4 is also promoted it self node to become the ACTVE. SC4 send the take-over request.

  • Unfortunately the node become ACTIVE is quiesced SC1, not standby SC4. So all synced data from ACTIVE may be lost
