Exapnd /tmp by mounting /tmp to a new harddisk and partition

1. Install new harddisk / create new virtual disk 
2. You may need to reboot in order for the kernel to recognize the new harddisk.
3. assume the new harddisk is recognized as /dev/sdc
   You may check the existence of the new harddisk by fdisk -l /dev/sdc
4. create new partition: fdisk /dev/sdcEnter the below command:
1. n  (new partition)
2. p  (primary)
3. 1  (partition no. 1)
4. accept default value for cylinder
5. w  (write changes to disk)
5. Create file system ext3 on the new partition: mkfs –t ext3 /dev/sdc1
6. rename the existing /tmp to /tmp_old
1. if /tmp mount on a separate disk
1. edit the /etc/fstab to make it mount at boot
2. add this line:
   /dev/sdc1  /tmp  ext3 defaults   0  0
3. if the existing /tmp is mount on a separate partition, change the existing /tmp mount to /tmp_old in /etc/fstab (if any)
4. mkdir /tmp_old
5. reboot the Linux
2. if /tmp is not mount on a separate disk
1. reboot in single user mode
2. rename /tmp to /tmp_old:
   Command: mv /tmp /tmp_old
3. create new directory for mount: mkdir /tmp
4. reboot the computer again to verify
7. Migrate everything from /tmp_old to /tmp
   cd /tmp_old
   find . -depth -print | cpio -pdlmv /tmp(You may need to add overwrite parameter (-u) to cpio if you are in second attempt to avoid excessive confirmation: find . -depth -print | cpio -pdlmvu /tmp)
8. delete /tmp_old content if everything works fine.
