Creating new swap and data partition disk in oracle linux on virtual box

In this article we will perform  ..

1. swap disk partition addition to virtual box Oracle linux machine 

2. data disk partition addition to virtual box Oracle linux machine 

Let's Begin  ..

1. swap disk partition addition to virtual box Oracle Linux machine 

Power off the machine and click on virtual machine setting , Go to Storage (Controller SATA) & click on middle symbol to create new disk in Hard Disk selector -->

Follow the steps ..

Selecting fixed size will pre-allocate disk space & will be time consuming ..

Start the virtual machine and login as root to add the disk into swap space ..

[root@oraclesrv dev]# fdisk -l sdb
Disk sdb: 10.7 GB, 10737418240 bytes, 20971520 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

 

[root@oraclesrv dev]# mkswap -c /dev/sdb

[root@oraclesrv dev]# swapon /dev/sdb

2. data disk partition addition to virtual box Oracle linux machine 

Follow the same step as Step 1 for adding disk into virtual machine .. Follow the further steps to add disk for u01 & data as per snap 

Start the virtual machine and login as root and perform as follow ..

[root@oraclesrv dev]# ls -lrt sd*

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.
