my problem started when I wanted to upgrade OMV to the latest version.
my nas is currently running OMV 0.5.
before I rebooted it, it had been up for almost a year.
before starting the upgrade I made a backup of the system disk with clonezilla.
then I rebooted again and couldn't get a network connection.
- fixed IP address => doesn't work
- dhcp => doesn't work
in the log of the router I see the request coming in and the router offers an IP address,
but the address is ignored by dhcpclient
I tried omv-firstaid but that didn't fix it either.
it's not a hardware issue. I booted the nas from a memory stick with some linux distribution
and this immediatly connected to the network.
I would like to avoid reinstalling from scratch because of all the setup I will have to do again.
