659008 - scl1-production-puppet-new: new centos 5 KVM in scl1

Status: RESOLVED FIXED

(Infrastructure & Operations :: RelOps: General, task)

Description

[Dustin J. Mitchell [:dustin] (he/him)]

To migrate scl-production-puppet (bug 659005), we'll need a new KVM instance in scl1.  The current system has

 1 CPU
 4 GB RAM (most of which seems to be cache)
 15 GB / (7.4 used)
 213GB /builds (9.0 used)

Based on http://ganglia1.build.scl1.mozilla.com/ganglia/graph.php?g=mem_report&z=large&c=RelEngSCL1&h=scl-production-puppet.build.scl1.mozilla.com&m=load_one&r=hour&s=descending&hc=4&mc=2&st=1306166623 I think we can make do with

 1 CPU
 1 GB RAM
 40GB /

Let's name the new host scl-production-puppet-new; we can swap the DNS record when we're ready to cut over to the new system.

Just because it's less disruptive to decrease than increase after the fact, I've built it with 2G of RAM (which also means 2G of swap) for those times when a bunch of machines reboot at once and slam it.  Please open a new ticket when you're ready to cut over and change the hostname/IP.
