Hi

I have a server with Debian 8. The disk ran full the other day and I deleted som large files and rebooted the system. Now it wont start up again.

It is hanging after "mounted filesystem with ordered data mode. Opts: (null)"

I have started the system with a rescue CD, but I cant find any logs containing anything about the boot and why it wont work.

What can I do?

I have tried to mount the drive and deleted some more files, but same problem.
