As part of the parent task to replace carbon as the DHCP/TFTP/APT/install-server, the networks private1-c-eqiad and private1-b-codfw have already been switched to use install1001 instead of carbon as DHCP and install1001 is already TFTP for all networks.
Please also configure network gear to make all other networks use non-carbon servers as DHCP, install1001 for eqiad, install2001 for codfw.
Since you already volunteered on IRC to do it, assigning directly.
Thank you!

Done. Now esams+eqiad use install1001 as DHCP server and ulsfo+codfw use install2001 as DHCP server.
Mentioned in SAL (#wikimedia-operations) [2017-01-24T12:23:55Z] <akosiaris> switch all networks to use install1001, install2001 as DHCP relay endpoint. T156109
@akosiaris Thank you! I have reinstalled planet2001 using install2001 and it worked fine. I will do some more tests for eqiad soon.
I also tested with prometheus1003 if the installer starts. It does.. (fails later at grub install but not related to this here).
finally tested with analytics1015 (unused spare system), installed trusty image from install1001. services on carbon were down too.
resolving now
reopening - I have one more request please. Can we please change install1001 to install1002 and install2001 to install2002? These are both VMs with consistent disk size and they replace 1001/2001. (one of them was a physical machine, the other did not have the right disks and just recreating them as -002 seemed easier and cleaner than renaming actions and installing across DCs.
I realize this might be on your last day before you are away for a while, please feel free to put up for grabs and i'll ask others.
@Dzahn, change what specifically? DHCP relay? ACLs for TFTP? ACLs for webproxy, Ganglia etc.?
@faidon I would like the DHCP relay changed from install1001 to install1002 and from install2001 to install2002. TFTP/webproxy/Ganglia should not need changes (that i'm aware of). They have already been switched to the newer machines.
It actually required a bunch of ACL changes for TFTP/webproxy/Ganglia. All of these plus the DHCP relay have been adjusted now across eqiad/codfw/esams/ulsfo.
