When eDirectory server is upgraded from 8.8.x to eDirectory 9.0, the upgrade process performs the disk space check during the DIB upgrade. The free disk space necessary in the file system, where the DIB resides would be equal to that of the DIB size. The messages of the disk space check would be updated in the ni.log and <Install Path>/novell/nds/ndscheck.log.
NOTE:The disk space check is required only during the DIB upgrade process. For more information, refer to Section 7.0, Upgrade Requirements of eDirectory 9.0.
