Symptoms

Zookeeper failed to start after 'update-server' from 18.5 to 18.7.
The subsequent pre-checks for 'update-storage' will fail with the following error.

 

# odacli list-jobscreate-prepatchreport -st -v 18.7.0.0.0
DCS-10001:Internal error encountered: DCS servers are not available on all nodes, pre-checks will not be successful.

 After reboot server, zookeeper didn't start automatically.

 # ps -elf | grep -i zoo

 0 S root 44606 44042 0 80 0 - 25845 pipe_w 09:18 pts/0 00:00:00 grep -i zoo

However zookeeper can be started manually.

# /opt/zookeeper/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
