install chi-node-05

we're starting to run out of space, especially DRBD disks, in gnt-chi:

root@chi-node-01:~# gnt-node list
Node                       DTotal  DFree MTotal MNode  MFree Pinst Sinst
chi-node-01.torproject.org 464.7G 247.7G 377.9G 27.2G 349.9G     3     2
chi-node-02.torproject.org 464.7G 247.7G 377.9G 53.1G 323.9G     2     6
chi-node-03.torproject.org 464.7G  49.5G 377.9G 44.2G 332.8G     2     5
chi-node-04.torproject.org 464.7G  49.5G 377.9G 16.3G 360.7G     2     5

so before we forget how to do this, setup a new node!

if this goes well, why not install all of them already. chi-node-07 is special and needs to be checked with upstream first.

checklist:

next step here is to run the fabric installer. having a checklist might help too, considering how messy this has been:

• bootstrap grml
• fix RAM (#40377 (closed))
• fix serial console?
• fabric install

new-machine checklist:

• partitions
• debian install and security upgrades
• hostname
• public IP
• reverse DNS
• working resolver
• root password reset

Post install checklist:

• add to spreadsheet
• tsa-misc
• bootstrap puppet
• add to nagios
• reboot
• dnswl (N/A)
• mandos
• ganeti install
• iSCSI cluster config
