Server boots but cannot access WebUI

[unburt]

Hi,

I have been using Unraid for several years. Last night I updated from 6.10.2 to 6.10.3 and all seemed well. This morning I tried to set up a VPN tunnel. I had some issue where the server stopped responding so I powered it off.

 

After power on, I was unable to reach the Web UI. Since I do not have a graphics card in the server, I powered it off again, installed a graphics card and attached a monitor to see the screen output. It was stuck in booting and I googled the last few output lines and found some suggested resolutions to delete vfio-pci.cfg from my USB (I did attempt passing through a GPU in the past and was not successful). I deleted the file and the system now boots and reaches the prompt and allows me to log in.

 

However, I still cannot reach the web UI. Do you have any suggestions on troubleshooting from this point?

 

I have checked the network cable, it is still attached. I unplugged it and rebooted Unraid, after it boots it shows that it has no ip address. After reconnecting the network cable, and rebooting Unraid, it shows its IP address. 

 

<edit>

I forgot to describe some of the mucking around that I did:

1. Last night, I had made a backup of my USB on version 6.10.2 prior to updating.

2. After I experienced issues, I used a macbook and used dd to create a disk image of my USB (presumably on 6.10.3)

3. I have copied the contents of my 6.10.2 backup onto the flash drive.

4. I have since mounted the dd image on my macbook and copied the contents of the disk image onto the flash drive 

 

I am currently in a state where I can log in to the console but I cannot reach the web ui.

In another topic I learned about the `diagnostics` command to create the diagnostics zip file. I have attached it here.

In the syslog, I've found that there are a large number of errors with `nmbd`, this seems to be related to samba? What might be the problem here or what steps could I take to resolve it?

If it is relevant, I believe a parity check may have been in progress.

I have resolved my issue by following the Restore From Backup article from the manual with the backup I created prior to updating to 6.10.3. I used the USB Creator on OSX with my backup zip file.

https://wiki.unraid.net/Manual/Changing_The_Flash_Device

 

I did still have to remove vfio-pci.cfg from the restored files though. And I had to run the make bootable batch file but otherwise I seem to be back up and running.

 

it is frustrating not really knowing what actually went wrong but I guess that is the beauty of having a backup. it doesn't really matter.
