SUSE OpenStack Cloud 8


After the disk went full where the log files resides, some of the services are down


Move/remove the empty log file, then restart zookeeper.service

monasca storm:
Open the /etc/storm/storm.yaml file. Verify there is a "storm.zookeeper.servers:" entry with an IP address specified (if not, then storm is misconfigured and may need to be fixed).

Using that IP, run '/usr/bin/ -server <ip>:2181', this will start a command line interface.
Run 'ls /storm' and verify there is a list.
Should look like looks like [assignments, backpressure, blobstoremaxkeysequencenumber, credentials, nimbuses, logconfigs, leader-lock, storms, errors, supervisors, workerbeats, blobstore]

Removing with 'rmr /storm' command and run 'quit' to log out of should clear out the broken references. Restart zookeeper.service,storm-nimbus.service and storm-supervisor.service to get it recreated.


Following error message in logs:

zookeper: at at org.apache.jute.BinaryInputArchive.readInt( ...
at org.apache.zookeeper.server.ZKDatabase.loadDataBase(

Issue is that an empty logfile (size is zero) or with invalid headers exists:

monasca storm:
org.apache.storm.utils.NimbusLeaderNotFoundException: Could not find leader 
nimbus from seed hosts [localhost]. Did you specify a valid list of nimbus
hosts for config nimbus.seeds?
