change containerd’s default data path
Identify the Current Data Path
1
| containerd config default | grep "root" # Expected output: root = "/var/lib/containerd"
|
Modify the following lines in /etc/containerd/config.toml:
1
| root = "/path/to/new/data/path" # the location where container data (images, volumes) is stored
|
Move Existing Data (if required)

3
| sudo systemctl stop containerd # optional
sudo mv /var/lib/containerd /data/containerd
sudo systemctl start containerd
