Hello Community!

I have a really strange problem with Unraid. Sometimes at random I can't access the WEB-GUI or connect via SSH. The crazy thing about this is, that the docker containers and VMs are still working.

For example, I can use Home Assistant (VM) or connect to my FileRun-Instance (Docker) and it even seems like it is downloading games to the SteamCache (Docker)...  But when I try to go to the web login at my servers ip it takes a very long time until the error 500 appears. If I try to connect via SSH it stops after I entered my password like this:

 

I had the problems for a couple of days now and it really makes me feel uncomfortable because I have to pull the plug on my server...

I have attached the diagnistics file from yesterday after I restarted unraid (by unplugging the server 😵 ) but I am not even sure if this contains helpful information?

 

I would be very thankfull if anyone could help me figure this out!

Little update... I connected a monitor to the unraid server and instead of the usual text I just have a black screen.

Just guessing, but the monitor probably needs to be connected before you turn on the server, otherwise your motherboard won't initialize the hdmi port

Normally the monitor turns off after a couple of seconds if it receives no signal (I tried the PCIe-graphics card first 😉).

With the mainboard HDMI the monitor seemed to receive a black image. Do you mean this, or should it just turn off if the port is not initialized?

Pressing keys on the keyboard may wake it up? Otherwise I think you'll need to reboot and figure out where to plug in the monitor until it lights up during boot.

 

Or you can wait for someone else to chime in  

I think the HDMI was correct (I unplugged the graphics card for debugging reasons now). I tried "waking" up the system with mouse and keyboard, but no success... 

 

So now after "hard resetting" the machine I have access again and pulled the diagnostics files again. Maybe this is worth something 😅

clearification

It happened again... something I noticed is, that whenever I have to kill my server, after the reboot it starts the parity check. This seems strange to me, because I turned of scheduled checks...

This means it's detecting an unclean shutdown, posting the diagnostics auto saved in the flash drive (/logs folder) might give some clues.

The folder looks like this:


Which file do you mean?

Latest one should be fine, it should be from the date/time you last rebooted.

I attached the latest one... Is there a difference between these files and the ones I sent before, that came from the diagnostics tool.

Also I enabled writing the syslog to flash - would this be of any help?

Currently set shutdown timeout is not enough, change from 90 to 150 secs (Settings -> Disk Settings), you can also stop the array and time how long it takes, than add a few seconds to that.

change from 90 to 150 secs

Thanks for the tip - Can this cause the WEB-GUI and SSH to become unresponsive?

Another thing I remembered is, I get Oout Of Memory Errors quite often... Maybe this is the cause?

applied proposed settings

That will only help with unclean shutdown. 

Same here, docker containers are running, but smb, webgui and ssh shares are not

Next time it's better to start a new thread, but please post the diagnostics

Hi,

 

I've been having this issue for the past couple of weeks.  Did you get to the bottom of the issue?

 

The Unraid WebUI has stopped responding via IP address but the UI for the docker apps are still accessible over the same IP.

Happy to start a new thread, how do I get diagnostics when the WebUI is not responding?  I'd don't want to keep restarting the server every time this happens.

The word diagnostics, in your post and mine and everywhere, is a link that explains how to get diagnostics.

Would just like to add that I am experiencing the same issue on 6.12.15, if RAM, disk usage (such as docker) is almost full, disk throughput is very high, webui and ssh become accessible, but all other features including docker, and vm's work fine. 

 

The only way to recover is wait for whatever process to finish or timeout, or hard reboot the server if the RAM, or when disk usage drops, or to force shutdown the server via button or power switch. From what I've noticed, about 50/50 success of pressing the shutdown button once and it shutting itself down. 

 

I particularly experienced this when Plex was transcoding into the docker image (separate issue that I've resolved), the docker image hit 100%, then webui and ssh access was lost.

 

Will also try updating to 7 at some point (had major networking issues with 7.0.1 last time I tried)
