Issue

  • After uploading a LAR file, a message "The file <filename>.lar cannot be imported: Unable to write temporary file" is displayed
  • lar_error.png

Environment

  • DXP 7.3, DXP 7.4, Quarterly Releases

Resolution

  • Liferay requires to create temporary files in the filesystem when uploading files. 
    • In Tomcat, the default temporary folder is $TOMCAT_DIR/temp.
  • The LAR files are also unziped in the temporary folder.
  • The solution is to increase the available space of the file system to more than double the size of the imported LAR file.
