My elastic cloud deployment is not replicating the indices after it got filled up 100%

Hi Team,

I recently upgraded the elastic cloud deployment to 8.15 version. After I made that all the new templates are unlinked with the lifecycle policy and data was keep on growing in the replica node. since it reaches the 100% disk space, it got deleted and allocated a new replication node automatically but it is not actively replicating the current data that is coming in.

Can anyone please tell me what needs to be done?
I even manually updated the number of replicas setting in the index template again just to double check.

Thanks,
Surya
