Cloudera quickstart VM comes with 64GB disk size. This size is not suitable for storing big data files in this VM. This post shows how you can increase size of disk for Cloudera virtual machine running in VirtalBox.
First you need to change size of the disk in VirtualBox's "Virtual Media Manager". Please shutdown your virtual machine before resizing your virtual disk.
Launch the "Virtual Media Manager".
Change the size of your disk to 200GB from 64GB and click Apply button.
Now start the machine. Once virtual machine is launched look at block devices present in the virtual machine by running lsblk command. Notice that size of drive sda is now 200GB but size of dm-0 55GB. The partition dm-0 is mounted as root partition. We need resize this partition and filesystem under this partition.
We will be using fdisk command for resizing the partition. Please take a backup of your data before doing this step any mistake can make your virtual disk unusable and you may loose all your data. Run the fdisk command on /dev/sda and print the partition table.
Now delete partition number 2. We will create this partition again with a larger size.
Now create partition 2 again with larger size. We use all the free space on the disk while creating the new partition.
Now write the partition table to the disk. After writing the partition table to the disk the virtual machine you need to restart the virtual machine.
After restarting the virtual machine we need to resize LVM partition which hosts the root partition. Now you can resize the physical volume in LVM using sudo lvm pvresize /dev/sda2 command.
After resizing physical volume we need to resize the logical volume using sudo lvresize -l +100%FREE /dev/vg_quickstart/lv_root command. This command will increase logical volume for 100% of free space. Now you can see LSize is 191.50G.
Now we need to extend file system size present in the lv_root partition. The mounted filesystem can be resized using sudo resize2fs /dev/mapper/vg_quickstart-lv_root command.
Now size of root partition is 189GB. Now you can store large files in this virtual disk and use this virtual machine for processing large files.
