** [tickets:#2948] rde: race between quiesced node and standby node become
active node**
**Status:** unassigned
**Milestone:** 5.18.12

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
