Root drive filled up and now things are broken

I need some help.  6.9.2. I think TVHeadEnd addon is a bit broken - and dumped a whole load of ts files in my root directory.  This is the second time this has happened. I deleted the *.ts files the first time and this time i thought I'd move them and see what they are to help in determining what is going on.

 

So tried a few things, restarted readynas and - sluggish performance, no shares mounted or available. log files showed dropbox start fail, email sending fail.

 

Anyway, the issue is now, admin login page will not get through to the dashboard - it goes the horizontal-bar screen then "ReadyNAS Admin Page is offline".

 

This is what I did from the start:

Shell in a box didn't work (typing name and then "enter" just resulted in "session closed"

Tried to enabling SSH - which would enable, then would reload the config page with SSH showing disabled.

Quickly enabled it and hammered NAS with PuTTY to connect. Successful

root log in and moved all TS files to my raid array directory and a folder

df is all good, 47% used instead of 100%

shutdown -r now works, but can't log in

systemctl list-units shows readynasd as active failed failed

htop shows no real issue - apache is up and working

 

I guess somewhere the full root disk has stuffed up some readynas core files or config or something?

 

Please help?! How can I enable diagnostics if I can't get to the readynas web config page?
