users cannot see any data in existing projects due to the error message below found in Atlassian log file
org.apache.commons.lang.exception.NestableRuntimeException: java.io.FileNotFoundException: C:\Jira\index\issues\_5zd.fnm (The system cannot find the file specified)
I am not sure how this file is created or how it could have been deleted but the .fnm file is not found in any of our backups. Any advise on how to recover from this error would be HIGHLY appreciated,
Thanks,
Bill
