LVM Storage Server Installation

Step 1. Boot from the Abiquo ISO

Step 2. Test the media (optional)

 

Step 3. Welcome screen

After you complete the previous steps, the graphical setup screen will appear. Click <Next>.

Step 4. Select your keyboard and click <Next>

Step 5. Partition the disk

The installer will search for any Abiquo installations and will allow you to partition the disk. You should select 'Review and modify partitioning layout', because the name of the volume group should be changed, as explained below.

Click <Next>. The following screen will appear:

Volume group name

The Abiquo LVM Storage Connector detects the logical volumes and names a storage pool after the volume group.

The VolGroup00 volume group should be renamed because Abiquo will display the volume group name as the name of the storage pool. In this example, we rename it to 'abiquo'. Double click the VolGroup00 label (highlighted) to get to the edit dialog.

Logical volume distribution

The default volumes that appear on the screen (for the operating system and swap) will use the entire disk, so we need to decrease their size to free some space. That free space is where the LVM storage agent will create the logical volumes.

In this tutorial, we are using a 20 GB hard drive. For a 20GB drive, you should resize LogVol00 ( / ) to use 8 GB and LogVol01 (swap) to use 1 GB, leaving 11 GB free that will be used as the LVM external storage. After shrinking the logical volumes and changing the volume group name to abiquo, click <Ok>, and then click <Next>:

Step 6. Configure the boot loader

Defaults are usually okay; click <Next>.

Step 7. Set up networking

Either use DHCP or manually configure the networking parameters.

a. DHCP

If using DHCP, click <Next> to go on. Or to set up networking manually, click <Edit>:

b. Fixed IP address

Under "IP Address" enter the storage server IP address. For "Prefix" enter its subnet mask (in CIDR notation or dotted format). Disable IPv6 support. Click <OK>. Back at the networking screen, enter a hostname for the server:

Enter the values under "Miscellaneous Settings" and click <Next>.

Step 8. Select your location and click <Next>.

Step 9. Enter your root password

Enter the desired root password for the operating system and click <Next>. Your Abiquo support representative will need this password to provide remote assistance.

Step 10. Select the type of installation

Select Storage Servers and then Abiquo LVM Server from the list and click <Next>.

Step 11. Ready to install, click <Next>

 

The installation process usually takes 5-10 minutes, depending on your hardware. You will get the following screen at the end of the installation. Click <Reboot> to continue.
