Resize the disk after an upgrade
After upgrading your Victus VPS plan the virtual disk grows, but Linux needs the partition and filesystem expanded to actually use the new space.
When you upgrade a Victus VPS plan, the underlying virtual disk is enlarged automatically. But the operating system still sees the old partition size until you grow the partition and expand the filesystem on top of it. This is a two-step process and is safe to run on a mounted, live root filesystem for ext4.
The extra disk space only appears after the VPS has been rebooted following the plan change. Check the plan in the panel and reboot once before resizing inside the OS.
See what the OS currently thinks
# Block devices and partition sizes
lsblk
# Mounted filesystem usage
df -h /You will typically see the disk (e.g. vda) reporting the new larger size, while the partition (e.g. vda1) and / still show the old size. That gap is what you are reclaiming.
Grow the partition, then the filesystem
# Install the tool if needed
apt update && apt install -y cloud-guest-utils
# 1. Grow partition 1 on /dev/vda (note the SPACE before the 1)
growpart /dev/vda 1
# 2a. Expand an ext4 filesystem
resize2fs /dev/vda1
# 2b. OR expand an XFS filesystem (uses mountpoint)
xfs_growfs /
# Verify
df -h /The device and partition number are separate arguments: "growpart /dev/vda 1", not "growpart /dev/vda1". Getting this wrong is the most common mistake.
Run findmnt -no FSTYPE / — use resize2fs for ext4/ext3, and xfs_growfs for xfs. LVM setups need an extra lvextend -r step; check lsblk for an lvm layer first.
growpart and resize2fs work online on a running system. Once df -h shows the full size, the new space is immediately usable.
