95% /var/lib/docker/overlay2/

On one of my SN i have 95% in /var/lib/docker/overlay2/
overlay 9.8G 8.7G 524M 95% /var/lib/docker/overlay2/

Do ai have to do something? When yes how to reduce it?

My Driveshare looks like:
/dev/mapper/vg0-DriveShare 1.8T 1.3T 427G 76% /DriveShare

You can try running:

docker system prune -a

That should clean up all unused docker components. Just cleaned up 4.3GB when I ran it. So worth a try.

Tnx. Now i have:

df -h
overlay 9.8G 7.9G 1.4G 86% /var/lib/docker/overlay2

Still 86%
