Cause

The CIFS (common internet file system) file type does not belong to Solr and is Microsoft's version of SMB with enhancements. It was likely generated in some way via Windows mounting of the drive, and it caused problems on startup because we normally check permissions on all files under the Solr on startup. Solr could not access this file, likely because it was added via CIFS mount and Linux does not understand that format.

Resolution

Remove the cifsFILENAME from the directory and services should start
