i will soon migrate this virtual machine to the new ganeti cluster. this will involve an IP address change which might affect the service.

please let me know if there are any problems you can think of. in particular, do let me know if any internal (inside the server) or external (outside the server) services hardcodes the IP address of the virtual machine.

it might be worthwhile removing this host from the varnish rotation until it's in place and dns has propagated and whatever. nothing should be talking to this host by IP address, except for all the places that have IPsec config.

the host was retired from unifolium. the only remaining match for the ip address is in the nagios check, and i think that will go away by itself after a while.

comment:5 Changed 9 months ago by anarcat

that was incorrect: a manual change was required in the nagios config, and has now been done.
