Double-check Your Disk space

We need to see how your disk is set first, to double-check our disk space Log in to your AlmaLinux server, then open a terminal and type the command below.

lsblk

This command will list all the block devices that are connected to your system, Under /dev/sda you will see the updated disk size.

sda 650G # Updated disk size
sda2 598G # Existing partition

Rescan the Disk

Sometimes the system does not immediately recognize the new disk space that you have added recently, so we need to make the system rescan the disk again. The following command will tell the computer to rescan the disk again.

echo 1 > /sys/class/block/sda/device/rescan

Increase Partition Size

After rescanning the disk, the new disk space will be recognizable for the system, so now we can make the partition bigger to use it. We will provide 2 options for this step, but we recommend using the first step.

Option1: growpart

If you don’t already have growpart tool, install it by using the command below.

yum install cloud-utils-growpart -y

To extend the second partition to use all available space by growpart tool, enter the following command.

growpart /dev/sda 2

To confirm that the partition size has increased enter this command in the terminal.

lsblk

Only use the second option only if option number one doesn’t work for you.

Option 2: parted

If the growpart is unavailable, use the parted by entering the following command.

parted /dev/sda

To make the desired changes use the comment below indivitually.

print # View the current partition table
