During the upgrade from 19.18 to 19.19, I got this worrying error

[root@odapdbc01 ~]# odacli update-dcscomponents -v
DCS-10008:Failed to update DCScomponents:

Internal error while patching the DCS components :
DCS-10001:Internal error encountered: Failed to enable ZooKeeper quorum TLS :DCS-12004:failed to copy file /opt/zookeeper/conf/storepassword to root@

This turns a temporary glitch. The solution is to (re)start thge DCS services on both ODA nodes:

systemctl start initdcsadmin 
systemctl start initdcsagent
