Moving /var onto different disk/partition

I moved the /var directory to a new disk/partition, this part worked well, but I forgot to delete/move the old /var path and it is still using space on / (root) partition. How could I delete the old /var without redo all the process? Any ideas? This is what I did so far: fdisk -l mount /dev/sdb /mnt/newvar/ df -h /mnt/newvar/ rsync -aqxP /var/* /mnt/newvar/ umount /mnt/newvar/ /mnt/var/ umount /mnt/newvar/ umount /disk2/ umount /mnt/newvar/ ls -la /mnt/newvar/ df -h vim /etc/fstab fstab content: UUID=c7c73822-b6e8-4aa4-a4b2-41a70c29568f /boot ext2 defaults 0 2 /dev/mapper/zabbix--vg-swap_1 none swap sw 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0 UUID="3195ad53-3aaa-418c-bdc0-d341e33d76d3" /var ext3 defaults 0 2 Result of the above command: df -P / /var Filesystem 1024-blocks Used Available Capacity Mounted on /dev/mapper/zabbix--vg-root 11758232 10103908 1033988 91% / /dev/sdb 25671996 8720916 15640360 36% /var
