Post Record action advice?

[mvallevand]

Those are all the type of considerations I was talking about if you leave thumbnails and timing generation on with post processing moving files. There is not enough testing and logs have shown there are problems if you keep them on. It might be better to generate them in post processing and turn the NextPVR generation off.

IsComplete() is also a problem with parallel processing and hopefully sub can look at the problem logs I have sent him

Thanks for the suggestion regarding the network driver.
TrueNAS detects that I have 2.5gbit. (4 of them in fact) (running a dedicated NAS specific motherboard)

It could be the way I originally setup the NAS using Raid Z2, which gives 2 redundant drives, which was pretty appealing to me at the time. 

Don't get me wrong, things seem to work adequately, but in the back of my mind, I have always pondered whether recording to a ridiculously fast drive would make a difference, especially over time after reading posts from other users utilizing the postprocessing function to do similar.

Previously, I had two large USB3 Seagate external drives, and used one for recording, and one for media storage, but always worried about no redundancy.

Currently I have NextPVR running inside a Windows 11 VM, so it is not a real mission to experiment with recording to a super fast m.2 drive that just about maximizes the theoretical thruput of the PCIe 4.0 bus.

So, bit of a mad science experiment on the cards, and whether it will truly improve things or not, it will not be too difficult to revert back to current working configuration, as can clone the VM, and perform the mods on it, spin it up, and see what occurs.

The other thing I wondered, is when configuring the NAS recording path in NextPVR, is if I should have more than one recording path?
ie.  Should I create additional recording paths, say one for each tuner?  eg.  4 paths for DVB-T and one path for Colossus 2 card?

Probably dumb I know, but just wondered if that might take better advantage of the 2.5gbit network segment, or doesn't it work that way at all.

(grin)  I seem to do a lot of wondering these days, as I lack the real skills to accomplish what I would like to do, so get the help I need from the brilliant folk on here!.

My issue wasn't detecting the 2.5Gb the connections was 2.5Gb and the switch light showed 2.5Gb. My throughput was still only 350Mb half duplex. The problem on dedicated Synology NAS hardware too https://github.com/bb-qq/r8152 so don't assume vendors get this right.

I have always pondered whether recording to a ridiculously fast drive would make a difference, especially over time after reading posts from other users utilizing the postprocessing function to do similar.

As a test, I've got 6 simultaneous UK recordings in progress (5x1080p and 1x720p) from my dual tuner and my 10+ year old 2TB SATA drive is sitting at between 0-5% utilization of with parallel timestamp and thumbnail creation.
Recording TV simply doesn't throw data at a disk quickly enough to trouble any HD.

I think a local drive is recommended for live TV buffer but an M.2 won't provide a better viewing experience that my old SATA.

The other thing I wondered, is when configuring the NAS recording path in NextPVR, is if I should have more than one recording path?
I don't have a NAS but from an NPVR POV, it doesn't make any difference if it's writing to \\truenas\folder1 or \\truenas\folder2 so unless TRUENAS has some sort of bandwidth limitation per UNC, then I can't see how this can help.

Pay heed to Martin's guidance (always) and check what your actual network throughput is, perhaps by copying a single large file with robocopy that shows transfer stats.

Wise words people.
Thank you again.

My NAS NIC's are 2.5G Intel i226, and the system hosting NextPVR is also Intel 2.5G.
I have TP-Link 5 port 2.5G managed smart switch, which is connected to a pFsense router, which also has Intel 2.5G.
Rest of the house uses TP-Link 24port gigabit switch.
But the NAS, NextPVR, Router and 5 port switch are on 2.5G.

Was looking at best way to test my NAS pool of drives to determine speed?.

[gEd]

An impressive setup for sure compared to my aged PC living under my TV and connected to a used 1GB Cisco switch!

My suggestion would be to copy a 2-4GB file from NPVR server to \\truenas\folder using robocopy and look at the throughput stats. you then need to see if this fits within the performance expectations of your system based on what others on the net (with similar systems) have. Given that NAS devices are designed to support multiple concurrent i/o transfers, a single file copy may not be representative but (as said) I don't know anything about NAS so my opinion is of limited merit here.

A quick search with Bing AI search engine returns this link that looks relevant.

Okay,  bit confused how I should configure NextPVR record folder.

As I am recording currently to NAS   '\\TrueNAS\TV Recordings'
And I want to now record to the NVME drive, which is 'D:\TV Recordings'

Do I remove the current NAS path completely, and replace with the NVME path above?
(as that is what I have done)

Doing some test recordings now to the NVME drive,  and when finished will try on the test.bat file and confirm is transferring to NAS.

What happens to my existing recordings that no longer show up, as I have changed recording path to the NVME drive?

Sorry for the dumb questions.

[gEd]

Leave the existing NAS path in place so that npvr can continue to find the recordings on that drive. the location of previous recordings is stored in a database.
you can change the default recording location to your NVME drive and all new recordings all be recorded onto that drive.

[three6zerocool]

Ok, thanks.
I re-added the original recordings location, and all my recordings are listed once more, and the NVME drive is the default.

Just waiting for a recording to finish, then I will test your script.

[three6zerocool]

I dropped a recording onto the test.bat, and it started moving the TS file and other files to the NAS.
Was a 10GB file, at seemed to take more than several minutes, and so far the cmd prompt window is still open with a flashing cursor.
Is that normal?

I can still hear the NAS seeking away, but the LED on the NVME stopped flashing, so presume it has finished.

Just tested Kodi client in the living room, and the recording indeed shows up and has thumbnail, and plays fine.
