2 NICS randomly switching IP every reboot

[kidlatngkavite]

Hi everyone.

 

I just installed a secondary NIC on my unraid server. I noticed that every reboot the ip address switches between this 2 NIC. I have to go to the console to reboot it several times until ip address switches to the correct NIC.

 

any network setting i might have missed to fix the ip addresses to the appropriate NICS?

 

thanks!

Do you mean that both NICs are set to DHCP and getting an IP from the same router?

Are you talking about the addresses assigned for eth0 and eth1?

 

Do the MAC addresses switch also?  (Do the MAC addresses 'stick' to the IP address or to eth0/eth1 assignment?)

Hi. The NICs doesn't switch. I use the mac address to identify if the NICs get the correct IP. The NICS get randomly assigned to eth0 or eth1, .

What Unraid release? Some NIC detection issues were fixed on 6.10.3, so make sure you're on that release.

I'm on 6.9.2.  I'll try your recommendation and update back here. Thanks!

Please report back if it solves the problem.

The update didn't work. IPs still switching.

Please post diags when the IPs are correct and also from when they switch, you can type diagnostics in the console if you lose access to the GUI.

Hi, I have uploaded the diagnostic files.

Thanks, network-rules.cfg is not getting created, let me see if I can find out why.

Can you run Unraid natively.

 

In this setup the network interfaces are not being detected by udev and hence no rules file is created, this results in random selection each time the system is started.

Hi,

 

Is this a limitation in running unraid on ESXi?

Virtualizing Unraid is not officially supported, doesn't mean you cannot do it, but some things might not work as expected, I missed you were doing it, though I didn't know it would interfere with udev.
