Mount / partition in rescue mode centOS

SSH the server in rescue mode

1. Create a directory “test” inside /mnt

# cd /mnt

# mkdir test

2. Mount the root partition on /mnt/test:

In order to identify the root partition we have to proceed as follows:

run

# fdisk -l

* As we know that usually in servers the default root partition is of 10-20GB we can identify the root partition easily by checking the size of “md1″ or “md2″ 

*Note commonly small size partition is the one

Now after identifying the root partition Run the command:

# mount /dev/rootpartition /mnt/test/

(replace “rootpartition” with “md1″ or md2″, whichever is the actual root partition)

3. Now chroot into the root partition :

# chroot /mnt/test/ (This makes us the root user of the server)

If you will reboot the server again you have mount the / partition.
