I am having some very erratic behavior with my server all of a sudden. I haven't changed anything.

 

I am on 6.12.8. I thought about updating but it was so unstable I was nervous it might crash during the process.

 

For two days now I have woken up to a white screen when I try to access the webui. Refreshing the page sometimes brings

up the webui. But then all the drives started disappearing, but oddly, the scrren would flash, no drives, half the drives, all drives.

Here  is a video.

During this time it seems like my docker stuff is online. My kids were watching TV through Emby.

I also had a hard time getting the diagnostics page to load because the webui kept crashing. Totally at a loss right now. Both days this

has happened I was able to SSH into the machine and reboot and it calmed down. This machine is 6 months old and has been very stable.

That's a new one, try booting in safe mode to rule out any plugin issues.

Just to clarify there are no further diagnostic options at that point. You are recommending to boot into safe mode and see if the problem persists?

 

And if it does not start looking at plugins and apps? It's weird because when I reboot in the morning all is well. And at least yesterday things seemed

fine all day. So I guess I can do that over night tonight and see how we look in the morning.

 

###EDIT Already started having the issue again, rebooted into safe mode. We'll see how it goes.

I booted the machine in safe mode. Was good for half a day or so then started doing the same thing. Drives disappearing.

 

I thought maybe it was my HBA card going in and out but it is not just drives that are on that card, sometimes cards on the

sata controller drop as well. Also the last time the NVME cache drive was also disappearing.

Anyone have any ideas I am at a loss. Concerned about my data.

This doesn't look like a hardware issue, try using a different browser, and make sure no ad-blocker/firewall is blocking the GUI.

Just woke up to the flashing again. Cleared cookies, made sure ublock was not running. When I refreshed I could get passed the login screen.

Tried on chrome (second browser) and same thing. I also noticed that two backups that run overnight failed because they couldn't access

my backup share on Unraid.

 

I don't have any fancy firewall running. Pihole is up but everything is green that is connected to unraid. Sigh

I would recommend redoing the flash drive, that will confirm if it's a /config issue, backup the current one first and then redo it and just restore the bare minimum, like the key, super.dat and the pools folder for the assignments, also copy the docker user templates folder, if all works you can then reconfigure the server or try restoring a few config files at a time from the backup to see if you can find the culprit.

I'm a little nervous about this as I have never done it. A couple questions.

1. Are you talking about using the same flash drive or a different one.

2. Will this potentially mess up my array somehow?

Same.

Not if you what I posted, and you can always restore the complete backup if there are any issues, though will probably continue with the existing issue.

Do you have a link to the documentation on how to do this properly?

You just need to copy (and then restore) the complete /config folder.

I know I am being super dense here but I don't understand this part.

How do I go about redoing it and restoring the bare minimum? I used the USB creator tool, but I got no option on what I wanted to restore it just copied the whole thing.

Are you talk about  starting from a clean usb and then copy pasting files into it. Not sure I can do this since the creator tool doesn't have the OS version I am on. So it would also be

an update in the process.

Already posted above, just copy the files/folder mentioned back to the /config folder on the flash drive.

Do I wipe the whole thing first? Won't that make it unbootable?

You recreate the flash drive using the stock install then just restore those files, I'm sorry, I don't know how to make this clearer.

Thanks that was all I was trying to clarify.

I'm on 6.12.8 and the only options are 6.12.9 and 6.12.10

Do you think it will be a problem to upgrade in the process as well?

Use 6.12.10, there shouldn't be any issues because of that.

Ok thank you for the help.

So I did this a couple hours ago. Also restored the shares. 

 

Sadly it is doing the same thing again. Not sure how to proceed.

I still don't see how this can be an Unraid issue, but try booting the server in GUI mode, then when the flickering starts, see if it also does it using the local Firefox browser.

Ok I'll try that. But it's more than flickering. The shares drop off and are unavailable at times. My over night backups from a proxmox server are failing.

 

So when it's doing it, the data may or may not be available. I'm not sure how to begin to troubleshoot that because even the nvme drive and the flash drive at one point were showing up in unassigned drives.

 

Also I can't really access the webui at all once it starts acting up. I just get a white screen.

Yeah, but I would expect that should leave something logged in the syslog, I assume the diags posted were after that happened?

Yes, it might have been after a reboot. I'll try to get one again while it's doing it. But at that point it is hit and miss if the UI is accessible.

You can enable the syslog server and post that after an event.

Great thanks I'll do that when I get home.
