My first NVMe (i hate this brand S*****P****), sometimes hangs periodically (marking the filesystem readonly) so 50-100% CPU usage and nothing more can be done. So I have to move some parts of it into another NVMe drive, here's how I moved docker to another partition
sudo systemctl stop docke
then you can edit
sudo vim /etc/docker/daemon.json
# where /media/asd/nvme2 is your mount point to your other partition)
# add something like this
{
"dns": ["8.8.8.8","1.1.1.1"],
"data-root": "/media/asd/nvme2/docker"
}
Clone your partition to that new partition (no need to mkdir docker folder):
sudo rsync -aP --progress /var/lib/docker/ /media/asd/nvme2/docker
mv /var/lib/docker /var/lib/docker.backup
Then try to start again the docker service:
sudo systemctl start docker
sudo systemctl status docker
If it all works, you can delete the backup of original data directory.
