** [tickets:#3263] rde: Cluster is unrecoverable after all nodes split-brain in
roaming SC**
**Status:** fixed
**Milestone:** 5.21.06
**Created:** Fri May 14, 2021 04:56 AM UTC by Minh Hon Chau
**Last Updated:** Fri May 14, 2021 04:58 AM UTC
**Owner:** Minh Hon Chau
In Roaming SC deployment, if split-brain occurs that separates all nodes apart,
in which each partition has one SC, we have all SCs becoming active. At rejoin,
all SCs detect themself as duplicated active to one of other SCs, they should
all reboot, ideally.
However, sometimes the last active SC is not detected as duplicated because all
the other SCs already reboot. The last SC does not find any others as active
duplicated to itself. As of this result, since the last SC is not healthy
throughout the split time, it's causing many errors for other nodes to rejoin
again after reboot.
