cifs drive

It is a shop bought drive.

An individual file:

/media/Recordings/2010_20130816213400.mpg


I have posted some messages from the log that I thought were relevant.
MythTV logs a lot, so it is hard to know what is relevant.

Hmmm...

I think Iwil create and delete a file.  Doing wat you ask would make the
file system inconsistant with the database

No space on drive, ofcourse... But here is what happened...

[q at bruce Recordings]$ sudo su mythtv
Password:
[mythtv at bruce Recordings]$ whoami
mythtv
[mythtv at bruce Recordings]$ groups
disk wheel video audio optical storage users mythtv
[mythtv at bruce Recordings]$ ls >trash
ls: write error: No space left on device
[mythtv at bruce Recordings]$ ls -l trash
-rwxrwxrwx 1 root root 0 Sep 17 19:49 trash
[mythtv at bruce Recordings]$ rm trash
