System Requirements

Before we begin, it is important to ensure that your system meets the minimum requirements for installing AlmaLinux 9.4. Here are the recommended system requirements:

• 64-bit x86_64 processor
• 4GB RAM (8GB recommended for KVM virtualization and other memory-intensive workloads)
• 20GB of free disk space (30TB in our case)
• Bootable media (USB drive or DVD) with AlmaLinux 9.4 ISO image

Installation Steps

Follow these steps to install AlmaLinux 9.4 on a large partition in Single User Mode:

1. Insert the boot media with AlmaLinux 9.4 ISO image into your system and boot from it.

   linux inst.stage2=hd:LABEL=ALMALinux-9.4-0 rescue inst.single

   Press Enter to boot into Single User Mode.

3. Once you are in Single User Mode, mount the root file system:
   mount /dev/sda1 /mnt/sysimage

   Replace /dev/sda1 with the name of your root partition.

4. Create a new file system on the large partition:
   mkfs.ext4 /dev/sdb

   Replace /dev/sdb with the name of your large partition.

5. Mount the large partition:
   mount /dev/sdb /mnt/data

   Create a directory for the root file system:

   mkdir /mnt/sysimage/data

   Mount the root file system on the large partition:

   mount --bind /mnt/data /mnt/sysimage/data

   Chroot into the root file system:

   chroot /mnt/sysimage

   Configure the network:

   nmcli device connect ens33

   Replace ens33 with the name of your network interface.

6. Install AlmaLinux 9.4:
   dnf -y install @base @core

   Configure the large partition:

   lvcreate -L 30T -n data vg_sys

   Format the large partition:

   mkfs.ext4 /dev/mapper/vg_sys-data

   Mount the large partition:

   mount /dev/mapper/vg_sys-data /data

   Create a directory for the root file system:

   mkdir /data/root

   Mount the root file system on the large partition:

   mount --bind /data/root /

   Create a file system table:

   /etc/fstab

   Add the following line to the file system table:

   /dev/mapper/vg_sys-data / ext4 defaults 0 0

   Save and exit the file system table.

7. Reboot the system:
   reboot

   Remove the boot media and press Enter to reboot the system.
