Problem:

My website down then I tried to access the admin panel it shows 503 error. So I tried to restart “systemctl restart lscpd” and its failed “Job for lscpd.service failed because the control process exited with error code.”. So it makes the admin panel can’t be accessed. Then, I figure it out it because the disk usage is full, after deleting a journal log then tried to restart again. but it still the same.

Do you see any error warning?
systemctl status lscpd
