If the management server has the following symptoms:
1. The root partition is nearly full
2. The du & df command output displays different results for the root partition
3. You have a mounting point for the CIFS file system
then you should check the mounting point.
Unmount the CIFS file system:
umount -i /mnt/mount_point_for_CIFS
List all the files at the mount directory:
ls -alh /mnt/mount_point_for_CIFS
Delete the files in the directory if they are unnecessary.
Then remount the CIFS file system:
mount -t cifs -o username=<Username> //X.X.X.X/sharedirectory /mnt/mount_point_for_CIFS
