Whenever I switch channels in LiveTV on my Mythbuntu Diskless Frontend, the Backend log shows the following entries.


2008-10-11 20:42:22.957 Current Schema Version: 1214
2008-10-11 20:42:22.979 Preview Error: Previewer file '/var/lib/mythtv/recording
s/live/7_20081011204219.mpg' is not valid.
2008-10-11 20:42:22.982 Preview Error: Run() file not local: '/var/lib/mythtv/re
cordings/live/7_20081011204219.mpg'
2008-10-11 20:42:22.995 Preview Error: Preview process not ok.
fileinfo(/var/lib/mythtv/recordings/live/7_2008101120421
9.mpg.png) exists: 0 readable: 0 size: 0
2008-10-11 20:42:23.087 AFD: Opened codec 0x82b15d0, id(MPEG2VIDEO) type(Video)


I NFS-mounted the stated directory as follows (output from mount):

server:/var/lib/mythtv/recordings on /var/lib/mythtv/recordings type nfs (rw,relatime,vers=3,rsize=131072,wsize=131072,hard ,nointr,proto=tcp,timeo=600,retrans=2,sec=sys,addr =192.168.1.190)

the actual mount is done in /etc/rc.local due to the Diskless behaviour of overwriting the fstab.

However, I searched for "Previewer file not valid" but could not find applicable hints.

Hi,

The error means that the preview process (The process that creates a preview image for display on the frontend) thinks that the file isn't local.

Maybe you can try setting the option on the frontend to always stream from the backend, that might solve the problem.

Thanks, Ian...

I tried that switch but I could not see any difference. Do you think there might be something wrong with the way I mount my NFS shares?

Mounting NFS seems to be a bit tricky with Mythbuntu Diskless clients, so I needed to add the mount command to rc.local and had to use the -n switch to avoid changes in the read-only mtab...

Hi,

I use samba/cifs to mount the videos from my backend, so I can't comment about NFS.
