Hi All, 

 

Had a electrical storm on Sunday and a power surge appears to have fried my router and the 2.5Gbe NIC port (Eth0) that was the ethernet connection from router to server. My AsRock board has 2 x NIC's (1 x 2.5Gbe & 1 x 1Gbe) and the 1Gbe might still work as the ethernet LEDs signify traffic being passed when connected etc.

 

When booting the server, I noticed that an error shows Eth0 'cannot find device'. For some reason I cannot get GUI to load, not sure if this is related to Eth0 not working or I have other issues. I have found instructions for changing the network settings within GUI but I am wondering whether able to edit a config file to re-assign Eth0 from the 2.5Gbe to the 1Gbe?

 

Any help is appreciated.

 

Regards

I would first go into the BIOS and turn off the 2.5Gb NIC.  Then see if things are working.

 

IF not, in the     /config     folder, rename the    network.cfg    file to   network.cfg.BAK        (You will have to shutdown the server to do this using your PC.)

 

If this does not work, connect up a monitor and keyboard to the server and boot it up.  (You probably have already done so to access the BIOS)  When it gets to the command line login point, login and type the following on command line:

diagnostics 

 

That will write the Diagnostics file to the   /logs   folder of your boot drive.   Now shut the server down with the following command:

powerdown

 

 Pull the drive and upload the Diagnostics file in a new post.

Thanks @Frank1940. I turned off the 2.5Gb NIC in Bios, connected LAN cable to 1GB NIC. Still same Eth0 error when booting.

 

Renamed network.cfg    file to   network.cfg.BAK  and rebooted and same error however took longer to boot and seemed to hang on the Eth0 error for a minute.

 

Was able to login and generate diagnostics file. See Attached.

I looked at the logs and there was a line in the syslog that said it was loading the drive for an Intel NIC--  (e1000e).  However, another line indicated that it failed to initialize.

 

Does that MB use a Intel 1Gb NIC?   If so, it may also be bad. 

@Frank1940 Correct, that is also my fear that it isn't recognising the Intel 1Gb NIC. Model number is I912v. Board is ASRock H470M-itx/ax if that helps. Does Unraid have a list of supported NICs? I googled but could only find forum posts rather than definitive list.

 

If I912v isn't recognised, is adding a NIC via PCIE the only solution?

Yes.   Unless you would want to do a MB replacement.   Often, folks will stick to Intel NIC cards as they are considered the top of the line.  virtually all NIC's are recognized by Unraid in the latest version (Be a bit careful if you are considering a 10Gb one and ask first about support) but don't buy the cheapest thing you can find. 

 

 

 

Thanks @Frank1940, appreciate the help.
