[mythtv-users] drive full? ringbuf1.nuv and / at 100%

[Roger Hanson]

I noticed some odd things yesterday.  Myth (installed using KnoppMyth) 
wouldn't log into the GUI (machine is both back and front end) but I 
don't remember the error, sorry.  Apache wasn't running at the time, 
either (but now it is).

But now, no data in the guide.  I looked at the drive(s) and see:
mythtv at pvr:~$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda1              3797912   3576208     29328 100% /
/dev/hda3             10505464  10505464         0 100% /cache
/dev/vg/myth         433888564 414760636  19127928  96% /myth

I don't remember the /cache folder being that full before, nor the root 
folder, either.

mythtv at pvr:/cache/cache$ ls -la
total 10505448
drwxrwxr-x  2 mythtv mythtv        4096 Jan  3 20:27 .
drwxr-xr-x  4 root   root          4096 Nov  7 08:05 ..
-rw-r--r--  1 mythtv mythtv 10747056128 Jan  5 02:21 ringbuf1.nuv
mythtv at pvr:/cache/cache$

Can I safely delete the ringbuf1.nuv - I believe it's just the live-tv 
stored video, isn't it?

Other things I can delete? (other than recorded shows)?

I see a bunch of this in the mythbackend.log
ERROR: file I/O problem in safe_write(), errcnt = 1: No space left on device
ERROR: file I/O problem in safe_write(), errcnt = 2: No space left on device
ERROR: file I/O problem in safe_write(), errcnt = 3: No space left on device

Thanks for reading.
