Disk Expansion After Reinstallation

Using Partitioning Tools: Use the fdisk or parted tools to delete and recreate the /dev/vda1 partition to utilize the entire disk space. For disks using the DOS partition table, here is an example procedure using fdisk:

  • Run sudo fdisk /dev/vda to start the fdisk tool.
  • Type p to display the current partition table and confirm the partition number for /dev/vda1.
  • Type d to delete a partition, then select the /dev/vda1 partition.
  • Type n to create a new partition, select primary partition, partition number 1, then use the default starting sector, and finally select the default ending sector to use all remaining space.
  • Type t to change the partition type, then select 83 (Linux).
  • Type a to make the partition bootable, if /dev/vda1 is the boot partition.
  • Type w to write the changes and exit fdisk.

Important: These operations will delete all data on the /dev/vda1 partition. Please ensure you have backed up your data.

Based on the disk information you provided, /dev/vda has a total size of approximately 42.9 GB, but the /dev/vda1 partition only occupies about 1.5 GB of space, starting from sector 2048 and ending at sector 3145727. To extend /dev/vda1 to use the remaining disk space, you need to perform several steps. Please note that these operations are high-risk; be sure to back up all important data before proceeding.

Step 1: Delete and Recreate the /dev/vda1 Partition

  1. Backup Data: Before making any modifications, ensure all data on /dev/vda1 is backed up.

  2. Use Partitioning Tools: Use the fdisk or parted tools to delete and recreate the /dev/vda1 partition to utilize the entire disk space. For disks using the DOS partition table, here is an example procedure using fdisk:

    • Run sudo fdisk /dev/vda to start the fdisk tool.
    • Type p to display the current partition table and confirm the partition number for /dev/vda1.
    • Type d to delete a partition, then select the /dev/vda1 partition.
    • Type n to create a new partition, select primary partition, partition number 1, then use the default starting sector, and finally select the default ending sector to use all remaining space.
    • Type t to change the partition type, then select 83 (Linux).
    • Type a to make the partition bootable, if /dev/vda1 is the boot partition.
    • Type w to write the changes and exit fdisk.

    Important: These operations will delete all data on the /dev/vda1 partition. Please ensure you have backed up your data.

Step 2: Extend the Filesystem

After recreating the partition and restarting the system (if necessary), you need to extend the filesystem to use the new partition size.

  • If the filesystem is ext4, use resize2fs: sudo resize2fs /dev/vda1

  • If the filesystem is XFS, use xfs_growfs: sudo xfs_growfs /dev/vda1

Step 3: Verification

Use df -h or lsblk to verify that the /dev/vda1 partition size has been extended as expected.
