In case of issues with Cassandra not starting in OpenContrail 4.x,
the system response of the doctrail analyticsdb contrail-status
command on the nal
nodes can be as follows:
== Contrail Database ==
contrail-database: active
kafka: active
contrail-database-nodemgr: initializing (Cassandra state detected DOWN.
Disk space for analytics db not retrievable.)
Workaround:
Remove all files from the /var/lib/cassandra/
folder:
rm -rf /var/lib/cassandra/*
Log in to the nal
node in question.
Restart the service:
doctrail analyticsdb service contrail-database restart
Verify the Cassandra status is active
:
doctrail analyticsdb contrail-status
Verify that the replication status of Cassandra is UN
:
doctrail analyticsdb nodetool status
Example of system response:
