ERROR 1101 : Could not allocate a new page for database because of insufficient disk space in filegroup . Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup.
Make sure there is enough Hard Disk space where database files are stored on server.
Turn on AUTOGROW for file groups.
