Hi all,

 

I woke up this morning to my Unraid server offline from the network. I haven't made any config changes recently, and was just using it last night. I can't access the webGUI or ping it from my client PC. I restarted the server and it seems to boot just fine, but can't ping anything from the bare metal Unraid CLI.

I see link lights on the NIC flashing, so it seems like something is happening and the NIC hasn't become unseated.

 

Any ideas why it's not accessible on the network? Diags attached.

Link detected: no

 

NIC is not detecting a link, try different cable or switch port, failing that try a different NIC.

So I have 2 NICs in the system. One is the onboard mobo NIC which is not plugged in, and the other is a 10G PCIe card.

I just restarted the server and booted into GUI mode to see if I could see anything. The system became available on the network, and I could access the WebGUI from my phone without a problem. 

So I rebooted back into regular headless mode and the webGUI is back to being inaccessible.

Eth0 may be swapping nic choice.  Quick test by swapping to the mb port.  If it connects, you know what happened.  Why is would be beyond me.

Examine the syslinux section under main, flash and see what's different between gui and cli mode.

So from the CLI, I restarted (what I assume is) the networking service with: 

sudo /etc/rc.d/rc.inet1 restart

 

And it seemed to come back online. This is odd to me because about 2 weeks ago, my NFS service randomly turned off and once I restarted it, it's been fine. Could there be a connection here?

In the diags posted no link was being detected on either NIC, so you won't have LAN access until one of the links is up, that should happen automatically, if a link is detected.
