Thanks Iridium

I'll try fsck and clean out any errors. I do occasionally power cycle the LE device which could have caused errors on HDD. I'll report back on how this goes.

Other thoughts:

The power supply I'm using has more than enough power for sure, its a 5V 3A adapter. The odroid came with 5V 2A.

Any idea if there are any logs generated on LE if the Hard drive was not getting enough power ?

do I not need to worry about auto sleep of HDD on LE ? I do want to turn off auto sleep of HDD's in any case.
Thanks !

My LE 8.2 running on odroid c2 keeps hanging every now and then. I believe the root cause is the USB hard drive going into sleep and then not waking up in a timely manner and failing. A reboot usually fixes the issue. But off late this has started happening almost daily.

When I SSH and try to access a folder on the hard drive via 'ls' command or any other way, that SSH session hangs too. Even Ctrl+C does not help. I have to disconnect session and reconnect. My SSH session works as long as I stay away from accessing anything on the HDD.

Here is the log entries from "journalctl -r" that makes me believe the problem is due to Hard drive:

Two questions:
- How do I disable USB auto-suspend for hard drives and make it persist after reboots.

- Is there any way to recover from the errors suggested in logs without reboot ? such as restarting a service or remounting hard drive ?

Ideally, I would want the hard drives to spin down only at night. But that is assuming that it will come back up day after day without these errors.

Please advice. Thanks in advance.

Thanks chewitt and mglae. I'll try that out. For now I added a sleep 8 and made it start after docker.service. It seems to be working as desired after several reboots.

Thanks mglae .

That would have worked well and been an acceptable solution. In my situation the problem is that this embedded device does not have a RTC which means it was starting with incorrect time and correcting the time during boot up via NTP. I think that is preventing the OnBootSec= from working as desired.

I removed everything and added the After=docker.service and that seems to have worked. It seems to kick off my script after Kodi loads even though I see docker starting up before kodi completes loading.

I'll keep a close eye on it and will revert if this starts to fail. But for now, I think anyone wanting to run custom scripts that deal with docker and need kodi running before it could use the same settings

[Unit]
Description=Script to autostart Privatebox App after kodi has loaded
After=docker.service

[Service]
ExecStart=/storage/.customScriptOnBoot

[Install]
WantedBy=multi-user.target 

Thanks for your help!

Thanks mglae .

This worked. My script is is able to find docker and execute it.

The only problem remaining is the timing. The script executes before docker daemon and Kodi has completed loading. Any suggestions on how to delay the execution of this service until kodi has completed loading completely? I have the following set in script but it doesn't seem to work.

After=kodi.service

Thanks vpeter .

This resolved the Format error message but there still are two issues:

1. The script does not get executed automatically upon boot after kodi loads.

2. When I start it manually 'systemctl start myServer.service' it fails with error message "docker: not found."

It looks like that the shell I enter into is not able to access the docker, because when I execute the docker command from command line in LE ssh I am able to get the desired results - docker loads and everything works.

I even tried this:
ExecStart=/bin/sh -c "/storage/.customScriptOnBoot"

and still get the same error "docker: not found".

Any other way to execute the script without opening up another shell? Thanks in advance.

I created a service under /storage/.config/system.d/myServer.service with contents:

[Unit]
Description=Script to autostart my Services after kodi has loaded

[Service]
After=kodi.service
ExecStart=/storage/.customScriptOnBoot

[Install]
WantedBy=multi-user.target

But this fails to run. I get the following error message in journalctl "

myServer.service: Failed at step EXEC spawning /storage/.customScriptOnBoot: Exec format error

I don't see where the problem is with the format. Please advice. Thanks in advance.

Hi ,

I"m able to successfully run a docker container and some scripts upon boot up via the use to autostart.sh. But some of my scripts need Kodi to be up and running. Adding sleep in autostart.sh does not help as it delays the loading of Kodi as well.

Since I am troubleshooting some other issues with the scripts and need to restart it manually as well (without system reboot) - I cannot add sleep because then

upon manual restart the sleep will slow me down while testing and troubleshooting.

Is there a way to run a script in Librelec upon boot but after Kodi has loaded ?

Thank you vpeter . Appreciate the prompt response.

Hi ,

I have a couple of alias that I'd like to set automatically when I log in to LE via SSH. I tried creating .bash_profile (with the alias commands) in /storage/ and made it executable, but that did not help.

What is the recommended way to create a .bash_profile equivalent on Libreelec ?

Thanks,

Pankaj

Platform - LE 8.2 for Odroid C2

Thank you mglae

Nevermind. I was missing the path to script that started docker container.

autostart.sh started from /storage/.config/ directory and the script I was executing was in /storage/. once I added path it started working.

Hi,

I need to start a docker upon boot and then run a couple of other commands after that so I've created autostart.sh under /storage/.config/autostart.sh and added the commands under it. I've also made autostart.sh executable. Upon reboot I do not see those commands being executed.

Is there anything else I need to do ? Where can I see logs for the attempt to run autostart.sh ?

Thanks in advance.

Thanks wrxtasy .
Hardware decoding is working quite well for all types of Videos. LE and Kodi Team has done an incredible job at making these.

Do you know if the GPU (on Amlogic S905) is able to encode as well ? (Transcoding to H.264) . The software transcoding is useless because it can only manage 2-3 fps.

Hi, I'm running 8.2.x on Odroid C2 and it works quite well in handling 4K Videos. GPU acceleration works for H.265 and H.264 codecs and probably other codecs too.

Can someone tell which Video Library is used to do GPU acceleration for Video codecs and does the Amlogic S905 SoC include required Licenses for decoding these codecs ? Or does one need to buy Licenses like one does if they were using Raspberry pi and wanted GPU acceleration for MPEG2.

For some odd reason, the hostname is now getting registered with DHCP/DNS Server. I didn't have to do anything.

I even changed the hostname in LE settings and rebooted. The new Hostname was immediately registered and resolves on my local network. Thanks for your help.

Thanks for the response, chewitt!

and I appreciate the tip about correct method of changing hostname. I'll do some digging on the DHCP/DNS issue and report back my findings.

I would like to change the hostname of LibreElec as I have more than one that I am testing out. I know I can go to /storage/.cache/hostname to change it.

But the problem I'm seeing is that this box does not register its hostname with DHCP/DNS Server - which is my ASUS Wireless Router.

Please advice if anyone has DDNS working for local network. (I'm not talking external IP using dons.org, I'm talking about DDNS within the local network)

I believe I'm running a fairly newer LibreElec with Kodi 17.6. (Don't know exact version as I'd changed the skin). I am SSH'd into it and can get the version number from CLI quickly If I know where to look. Thanks.
