Solr not available since latest update

Original Question or Issue:

Following the latest FileCloud update, the Solr service was unavailable and FileCloud search functionality was affected.

Environment:

Product - FileCloud Server
Version -
Platform - Linux

Steps to Reproduce:

Error or Log Message:

Review the Solr log:

/opt/solrfcdata/var/solr/logs/solr.log

The following errors were observed:

INFO (main) [] o.a.s.c.SolrXmlConfig solr.xml not found in SOLR_HOME, using built-in default
INFO (main) [] o.a.s.c.SolrXmlConfig Loading solr.xml from /opt/solr-9.10.1/server/solr/solr.xml
ERROR (main) [] o.a.s.s.CoreContainerProvider Could not start Solr. Check solr/home property and the logs => org.apache.solr.common.SolrException: Could not load SOLR configuration

Defect or Enhancement Number:

Cause:

The configured SOLR_HOME was missing the required solr.xml configuration file.

As a result, Solr attempted to load the default solr.xml from:

/opt/solr-9.10.1/server/solr/solr.xml

However, Solr was unable to load the required configuration and failed to start.

Resolution or Workaround:

Review the Solr logs to confirm the configuration-loading error:/opt/solrfcdata/var/solr/logs/solr.log
Verify that the required solr.xml configuration is available in the configured Solr home directory.
The working solr.xml configuration was provided from:/opt/solr-9.10.1/server/solr/solr.xml
Apply the appropriate solr.xml configuration to the configured SOLR_HOME.
Restart the Solr service:

systemctl restart solr.service

6. Verify that the Solr service starts successfully and monitor FileCloud search functionality.

Reference Configuration File

Download the working solr.xml configuration file from:

Download solr.xml

Notes:

Solr not available since latest update

Solr fails to start after a FileCloud update due to a missing solr.xml configuration file in SOLR_HOME. Restore the correct configuration and restart the Solr service to resolve the issue.
