Disk Expansion After Reinstallation
Use partitioning tools: Use fdisk
or parted
tools to delete and recreate the /dev/vda1
partition to utilize the entire disk space. For disks using a DOS partition table, here is an example using fdisk
:
- Run
sudo fdisk /dev/vda
to start thefdisk
tool. - Enter
p
to display the current partition table and confirm the partition number of/dev/vda1
. - Enter
d
to delete a partition, then select the/dev/vda1
partition. - Enter
n
to create a new partition, select primary partition, partition number 1, use the default starting sector, and select default for the last sector to use all remaining space. - Enter
t
to change the partition type, then select83
(Linux). - Enter
a
to make the partition bootable, if/dev/vda1
is the boot partition. - Enter
w
to write the changes and exitfdisk
.
Important: These operations will delete all data on the /dev/vda1
partition. Make sure you have backed up your data.
Based on the disk information you provided, the total size of /dev/vda
is approximately 42.9 GB, but the /dev/vda1
partition only uses about 1.5 GB of space, from sector 2048 to sector 3145727. To expand /dev/vda1
to use the remaining disk space, you need to perform several steps. Please note that these operations involve high risk, so be sure to back up all important data before proceeding.
Step 1: Delete and Recreate the /dev/vda1
Partition
Backup data: Before making any modifications, ensure all data on
/dev/vda1
is backed up.Use partitioning tools: Use
fdisk
orparted
tools to delete and recreate the/dev/vda1
partition to utilize the entire disk space. For disks using a DOS partition table, here is an example usingfdisk
:- Run
sudo fdisk /dev/vda
to start thefdisk
tool. - Enter
p
to display the current partition table and confirm the partition number of/dev/vda1
. - Enter
d
to delete a partition, then select the/dev/vda1
partition. - Enter
n
to create a new partition, select primary partition, partition number 1, use the default starting sector, and select default for the last sector to use all remaining space. - Enter
t
to change the partition type, then select83

to make the partition bootable, if/dev/vda1
is the boot partition. - Enter
w
to write the changes and exitfdisk
.
Important: These operations will delete all data on the
/dev/vda1
partition. Make sure you have backed up your data.- Run
Step 2: Expand the File System
After recreating the partition and restarting the system (if necessary), you need to expand the file system to use the new partition size.
If the file system is ext4, use
resize2fs
:sudo resize2fs /dev/vda1
If the file system is XFS, use
xfs_growfs
:sudo xfs_growfs /dev/vda1
Step 3: Verify
Use df -h
or lsblk
to verify that the size of the /dev/vda1
partition has been expanded as expected.
