Unable to record to NAS

[belgar]

Have problem recording to a NAS.
The recording works fine when recordings to a local HD.

This is my NRecord.log:

nrecord.exe, nextpvr.exe, NDigitalHost.exe are allowed in windows firewall.
using NextPVR 2.6.2

It's probably related to file permissions on your NAS.

The recording service runs as the 'localsystem' account, and it's most likely unable to access the \\RATAN17NAS\DiscStation share, or doesn't have the permission to create files.

Try using the IP of the NAS, it could a problem with the master browser. If that fails it is likle a permission error with the NAS blocking access.

tnx for the answers.

Sub: how do i change the recording service to be able to access the NAS?

Tried IP, same problem:

Edit: I can access the NAS from the computer that is holding the recordings, and move the recordings manually.

Sub: how do i change the recording service to be able to access the NAS?

I would fix it by changing permissions on the Recordings folder. Give "Full Control" permission to "Everyone" ... This might help ... http://www.tomshardware.co.uk/forum/1276...ve-windows

DiskStation is also an odd sharename. That is often the server name for a Synology NAS

Well, it is a Synology NAS. Activated the "guest" account and it worked, recording to the NAS right now.
Only tempory, but a fix for now.

[GSpanFan]

Even though this thread appears to have died a long time ago, I thought I'd leave a note here about using a Synology NAS in case it would help someone else.

I had the exact same problem as the OP and couldn't get NPVR to record to my Synology NAS. I got the exact same error in the logs about "Invalid file sent to StartParallelProcessing..." I spent a lot of time messing with the user permissions in DSM to try to get the correct read/write permissions on the NAS.

It turns out getting the permissions right on the NAS is only half of the problem. What's not stated above, but would be really helpful to anyone else try to get this to work is to realize that you MUST select the directory that you'd like to record to on the NAS in NPVR under "Settings ... Recordings ... Add ..." and then go into "Network Places ... DISKSTATION ... [Recordings Directory]". This selects the UNC name for the shared directory (e.g., "\\DISKSTATION\TV Recordings"). If you are like me and set up a mapped network drive on your Windows machine (e.g., "N:\" mapping to the TV Recordings directory), you cannot simply select the mapped network drive because apparently services running on the localsystem account can't access mapped network drives.

The other part above, about setting your guest account to have access to the selected recordings directory, appears to also be required because the DSM log indicates that the [guest] account is accessing the recordings directory during recording. There may be some more elegant way to set this up using permissions and setting up new specific accounts, but I'm reluctant to run the NPVR software as something other than localsystem for fear that it will mess up the ability of NPVR to access the needed system level resources that the localsystem account provides.

Well there you have it. Hope this helps someone!

[mvallevand]

I wrote a utility called ShareHelper that you should be find in the forums that does map drive letters for Local System.
