Restarting services fails to start after Solr. Services can manually be started one at a time
Solr's debug.log shows error
Found multiple cores with the name [writer], with instancedirs [/var/cb/data/solr5/cbevents/cbevents_YYYY_MM_DD_SSSS] and [/var/cb/data/solr5/cbevents/cbevents_YYYY_MM_DD_SSSS]
Coreservices debug.log shows error
<err> cb.utils.solr_client - Request to http://localhost:8080/solr/cbalerts/select failed with error <404 - Not Found>.
Environment
CB Response Server: 6.x
Cause
Multiple cores with the name 'writer' prevent Solr from starting properly
Resolution
Connect to the server's command line interface
Stop services
Edit the core.properties file of the cbevents core with the older date
vi /var/cb/data/solr5/cbevents/cbevents_YYYY_MM_DD_SSSS/core.properties
Change the name field from 'writer', to the name of the core/folder
name=cbevents_YYYY_MM_DD_SSSS
Save and close the file
:wq
Start services
Additional Information
In a clustered environment, the error may appear on any of the active nodes. Steps to rename the core must be performed on the node with the error
Watchlists will show Error until the next time the back-end job to run the watchlist has completed
An editor besides vi can be used to edit core.properties
