Thanks for trying to help. I realise I should have posted the configuration as I did in the earlier posts about this. Its a 4GB RPI4 with a 120GB SSD or LibreElec & Kodi with a self powered 6TB HDD for films, both plugged into USB 3 ports, dongle for USB mini keyboard plugged into a USB 3 port on the 6TB HDD& Haupage dual tuner plugged into USB 2 port with TVHeadend. Connected via powerline ethernet to a mixed Windows (3 laptops, 1 desktop all on powerline) & Linux (1 laptop using wifi) LAN. I transfer stuff to the 6TB HDD via SAMBA.

The RPi3 setup had two RPi3s both running off microSD cards, one with the Haupage tuner and the other HDMI to the TV, both plugged into powerline.

With the RPi3 setup, started back in 2018, I have not experienced corruption, with the RPi4 setup I don't think it even managed a week without corruption.

Basically I'm still trying to understand why so I can stop it happening and start using the RPi4.

Quote from Da Flex

I was talking about A/V streaming buffer, because you didn't mentioned a specific buffer. Kodi's default setting includes Samba caching into RAM. Maybe you have to increase the "memorysize" parameter to keep the whole Samba cache in RAM.

I was just asking about any buffer that might need flushing to an external USB drive. Something causes LibreElec/Kodi/RPi4 to corrupt an attached 6TB HDD. This does not happen with the RPi3 and its older s/w. What I need is to identify why so that I have a chance of stopping it happening and I can switch over to the RPi4.

So back to the question - does LibreElec/Kodi/RPi4 flush any outstanding buffers to an external USB HDD before rebooting or powering off?

Does that include access over SAMBA, just writes to its databases or what?

I've had corruption on my 6TB HDD again. I had been looking at different skins and I had rebooted / powered off the Pi a few times and I had made changes to the data on the HDD so my latest wondering is does LibreElec flush the buffers to a USB connected drive and wait for that to complete before either rebooting or powering off?

So far I've managed at best a week without corruption so for that and an issue with playing back recordings from TVHeadend I've sent the Pi on sabbatical for a few months.

Thanks to those who've helped me so far and as Arnie says "I'll be back"

Yes, your diagram is what I meant by that option.

Unfortunately, you seem to have conflicting requirements. You cannot have an isolated system with the two Pis and connect to one of them from outside of that system. Just can't be done.

Its worth going back and looking at what you're trying to achieve. A few questions

1. why do you want the separate file server, what is its purpose?

2. why not connect the SSD directly to RP2 which WILL give you the maximum speed connection?

3. what speed is actually needed to stream 4k60Hz iso files (someone else might be able to answer this because I can't)?

Its an interesting approach, but unless you are planning to add more nodes in I'm not to sure what you're trying to achieve. Why not just plug the SSD straight into RP2?

I have no idea if this will work (mainly because I've not tried it) but two thoughts did occur 1) enable wifi on RP1 and use that to connect to the router or 2) pop a mini hub in, plug into RP1 and make the other connections through that that would allow the router to be part of the setup.

Thanks for the info. I loaded the 16/9/22 nightly (I was on the 4/9/22 I think before) so that I included the latest update to SAMBA and am pretty much back to where I was before I started the upgrade ..... I think <VBG>

I'm bending my brain trying to understand the Amber skin enough to make a small mod so I won't be upgrading for a while, in fact if the 16/9/22 version works I may just wait until the release version.

Checked it out and yes it does "stutter" a bit on live TV. When you say "deinterlacing on your LE device" do you mean the TV or the RPi?

"LE has no knowledge about the used kodi in an update "

I'm surprised but OK

"If something goes wrong with a nightly then restore your backup"

Simply restoring the backup means that the newly installed nightly remains in place so I need to do a clean install and then restore the backup. Earlier on (several months ago) I did try cloning the SSD to an HDD but whilst both were 120GB devices they wern't identical and even though I used clonezilla and told it to ignore the size difference (loads of empty space mainly) the clone would not work. If there's a better way I'd be grateful for being instructed.

"or stick to official release builds."

I would have done if they'd worked. I'm using the nightlies because they have fixed many of the problems I'd been having.

I know - I was in IT for a long time at both developer and manager level and I've seen some major bloodshed.

On a totally unrelated subject I did look at the SD burner and QT, I spoke to several people I'm still in touch with in the development community - the general feeling was if it involved QT run away quickly.

Sorry, I wasn't being ultra clear. Rather than inform people partway through the update process they should be informed BEFORE it starts so that they can make a decision based on knowledge about a specific upgrade.

Part way through the process your software decides which addons are going to be permitted so the technology is there. Why not move that check to the front of the queue so the process can be aborted is desired.

I did make a backup before carrying out the upgrade. I also ran an export on the database and I'm backing that up now. When that's finished I'll try rolling back again.

I'll have a look, but I tend to watch live TV on the TV not on Kodi so I wouldn't have noticed that.

Is there some way that you can warn people that installing an upgrade from the nightlies will result in an addon being removed. I have very few addons - two skins, one visualisation and TVHEadend (version 4.2). As part of the upgrade process I was informed that TVHeadend had to be removed. I've installed 4.3 (Alpha) and that seems to work BUT I now have a lot of messing about to reconfigure everything.

Thank you for that - new keyboard now needed due to coffee spluttering!

And yes switching to matroska does seem to have fixed it.

I think this post belongs here rather than in the PVR group. Using TVHeadend (4.2) I recorded an episode of Doc Martin with stream profile of "pass". Playing it back lip sync was out and it was "stuttering" sort of freeze of a 10th of a second to give jerky movements.

I copied the .ts file to a memory stick, plugged it into one of the TVs USB ports and playback was perfect. I've recorded 3 other programs to test (different times, different channels) with the same result.

Recordings are being saved onto the SSD that Kodi runs from so to eliminate that I copied the .ts file onto the 6TB HDD I store my films on. Still stuttering on playback.

I'm guessing the issue is caused by ffmpeg so I'm going to try changing the stream profile to "matroska" and see if that helps. I'll report on that later today.

OK, I'll just disconnect once a week and hook up to Windows to check the disk - just until I'm sure things are working properly - fingers crossed

heitbaum posted the above in August. Is it still correct? I was hoping to be able to check my 6TB disk via ssh whilst it was still attached to the RPi4

I don't wish to be contentious but Windows & RPi3 LE 9.2.8 (I think) have worked fine since 2018. Switching to RPi4 & LE10 - not handling mp4 file correctly, moved to LE11 CEC problems & SAMBA problems. Or to put it another way I don't think its Windows fault.

I have FileZilla (similar to WinSCP I assume) but, unfortunately, I didn't think to try it. But a simple disk copy should be no problem especially with oodles of space left.

The 6TB disk is attached to the RPi4 by USB cable into one of the USB3 ports, the SSD holding LibreElec and Kodi is in the other. The filesystem is bog standard NTFS - again working perfectly since 2018 on the RPi3. The disk is the one that was corrupted several times but just worked happily when connected to the RPi3 for the last few weeks.

I have no idea how to investigate. If you have any suggestions I can follow I'm interested.

I'm having my latest attempt to switch to the RPi4. It seems to have gone all right (to early to really tell yet) apart from one weird phenomena. In music videos I have a (downloaded from YT) small clip from Medieval Babes. The title is Gaudete. When I tried to play it I couldn't and investigating I found the mp4 was missing (the jpg & nfo are there). When and why the mp4 isn't there I'm not sure - it is on my backup disk which was refreshed this morning whilst I was still on the RPi3 so I suspect importing the music videos did it (whatever it is).

I thought - OK I'll copy it back - which is where I get the weird message that the file is to large - we're talking about a roughly 5MB file on a 6TB disk with a couple of TB spare!

Even weirder if I change the name from Gaudete.mp4 to xxGaudete.mp4 it copies across just fine.

I don't know if any other files are missing yet - I'm off to write a small program to check everything out.

Anybody any ideas?
