There seems to be a problem with the TV Server when a networked drive is selected to be used as the timeshift directory. I wanted to use my RAID 5 file server because it has faster write speed than the HDD on my MP Server which would help with any problems caused by slow write speeds. The problem was when I tried to watch TV, I kept getting the error "Cannot start timeshifting. No audio or video detected." When I switched the tineshifting directory back to a local disk everything works fine. Below is the TsWriter log:

Hi,

Well, for some reason it thinks there isn't enough disk space. How much space do you have on your RAID? What type of RAID is it? Does it need drivers?

I know that it isn't possible to determine the amount of free space on a network share (not necessarily a drive). Does Windows show how much space is free on the drive? Maybe MediaPortal can't tell if there is enough space?

I think you need to give the developers a bit more info.

Best wishes,

Mark

MP usually needs UNC paths for network shares. Not sure if this is possible with NAS. Can you change from z:\Timeshift to \\NAS\timeshift instead? (or whatever else you call your NAS module).

 

[SciDoctor]

This could be an odd bug as if you check the 'disk quota' page in the TVsetup, Network drives aren't listed.

 

[crimz]

Using unc like "\\server\timeshift" doesent work... Mediaportal configurator crash/freeze/no respond...
But it wrote changes to config file. So when i started mediaportal, i got the "cannot start timeshift....." immediately

Pretty much the same result using z:\

Have to change back to my D: drive for timeshift/recording.

This has been a problem for me using dedicated NAS boxes, like Synology 207, DLink DNS-323 and there is a problem when i use my Windows Home Server. (i use a 1gb network)

Windows has always reported correct space avail.

 

[hobbes487]

Yes, I saw that the error was that there isn't enough disk space, but this can't be true, because I have 700GB free on the network share and windows shows this properly. I can try to use \\NAS\Timeshifting tonight when I get home, but it sounds like that won't work either.

I'm seeing a similar problem with my setup, last night I configured my recording directory as a mapped share on my Linux box and MP refused to record. I'll have a trawl through the logs later and post back here.

 

[Breezec]

The Tvservice runs as "Local system account". This account does not have the same permissions on the network as the logged in user. Can this be the problem ?

 

[crimz]

I really doubt that... but if you are willing to try, and report your experience that would be great...

(have several other services running that is highly network-related with the same priviliges..)

 

[Breezec]

I don't know what kind of server hobbes is using, but if it's a Windows server, "null session shares" has to be enabled before "Local system account" can write files to a network share.
I can test at home later today. (Had to enable null session shares for MCE to record to fileshare earlier this year).
