During the upgrade from 19.18 to 19.19, I got this worrying error
[root@odapdbc01 ~]# odacli update-dcscomponents -v 188.8.131.52.0 DCS-10008:Failed to update DCScomponents: 184.108.40.206.0 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 email@example.com:/opt/zookeeper/conf/storepassword.
This turns a temporary glitch. The solution is to (re)start thge DCS services on both ODA nodes:
systemctl start initdcsadmin systemctl start initdcsagent
