LevelDB gets corrupted and Ports are not up when when activemq is
stopped on servers
ActiveMQ version: 5.13.2
Brokers:3
Zookeepers 3.4.8 (3 nodes cluster)
We have upgraded our activemq architecture to new version 5.13.2 which
supports leveldb.
After upgrading to new architecture,we are facing the issue that failover is
not happening successfully on the nodes.
Ports(8161,1099 and 61616) are not getting up on the server afetr failover
or when the activemq service gets stops on the servers.
When we check the activemq console,we get exception message "Exception
occurred while processing this request, check the log for more information."
We have checked the logs and observed that leveldb gets corrupted each time.
To resolve this, we do the following on all the 3 nodes:
Stop activemq service on servers
Stop zookeeper on servers
clean leveldb and create fresh leveldb with the required owner and
permissions
Start zookeeper on servers
Start activemq service on servers
Can you please check this and suggest us the permanent solution for this.
Please let us know if more details required from our end.

A three-broker master-slave cluster using shared-filesystem KahaDB will
work, provided that you have a supported shared filesystem (i.e. NFS v4)
that's accessible to all brokers.

We are using ActiveMQ version: 5.13.2 .Will moving to kahaDB instead of
levelDB be feasible in this current architecture?

Please be advised that LevelDB is no longer supported. If it works for you,
great. If not, you have the source code and are welcome to troubleshoot it
yourself. Otherwise, you should consider moving to KahaDB or JDBC for your
persistent store.
