- The ring tab of a DC appears greyed out
- Errors related to the
/var/lib/datastax-agent/tmp/persistent/dsr/repair-service.dbappear in the agent log
- Problem only occurs with tarball agents: issue seen on 6.5.3 and potentially from 6.1.7 - under investigation
- OpsCenter 6.5.3
- The content of the ring tab in OpsCenter shows the nodes greyed out with an unknown status
- Datastax-agent output some error as per the excerpt below
WARN [C3P0PooledConnectionPoolManager[identityToken->xyz]-HelperThread-#0]:07:02,397 com.mchange.v2.resourcepool.BasicResourcePool$ScatteredAcquireTask@7c47eac7 -- Acquisition Attempt Failed!!! Clearing pending acquires. While trying to acquire a needed new resource, we failed to succeed more than the maximum number of allowed acquisition attempts (30). Last acquisition attempt exception:java.sql.SQLException: path to '/var/lib/datastax-agent/tmp/persistent/dsr/repair-service.db': '/var/lib/datastax-agent' does not exist
This error was potentially introduced with OpsCenter 6.1.7 and the Distributed Subrange Repair (DSR) feature. The tarball agents appear to be looking for a directory that only exists by default with the packaged installers
The problem was only noted after OpsCenter is restarted but agents kept running.
- Go to the cluster configuration file in opscenter. ie:
- Add the following section redirecting the agents to a valid temp directory (in the example below, make sure the user running the agent can read/write/execute to the folder /path/to/agent/tmp):
tmp_dir = /path/to/agent/tmp
This issue is escalated to development under OPSC-15533 for further investigation.

Alternatively, the release notes for newer versions would contain the fix reference when implemented. ie, for OpsCenter 6.5.x:
