DHCP Breaks Randomly
-
I have a FOG 1.2.0 server running on Ubuntu 14.04.3. I have been imaging for a day and a half now, and I have completed around 200 successful images. I came in this morning and was getting ready for the first batch of 36 machines. All but four PXE booted properly, so I just tossed them into another pile and started without them. The 32 that were left finished just fine like all the others. I set up the next run, and now none of the clients are getting DHCP addresses from the server. I have restarted the server (virtual) and the host. I restarted the switch, and I have not changed any settings in FOG. It has just decided to stop working. I have restarted the server several times, and for some reason I can’t always access the web interface. This server was 100% functional yesterday so I have no idea what has happened to it overnight. I have at least 2-3 more runs to complete before the day is out, so any assistance is greatly valued. I’ll be sticking around the forum to be sure and see your reply promptly.
Thanks!

To me it sounds rather simple. Your dhcp server has run out of IP’s to hand out.

That would make sense. I assumed that FOG did not have very long lease periods. So if it doesn’t recycle IP’s, how do I clear the current leases?

@arduinoAndMore You could expand the current scope… 1.2.0 only gives 254 addresses by default.
change your dhcp configuration file to expand your scope.
It’s really important to do this correctly - just saying. make a backup of the file as it is.
Then when you’ve made your changes - restart dhcp

SOLVED: Had to delete the /var/lib/dhcp/dhcpd.leases file. Started working again like a charm. Thanks again!
