639628 - create vm image to host buildbot-master4 in scl1

Status: RESOLVED FIXED

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

Description

[Mike Taylor [:bear]]

Please create a new 64bit OS vm image so we can migrate/install buildbot-master4 on it

Comment 1

[Zandr Milewski [:zandr]]

bkero- from hallway conversation, current 64-bit CentOS is probably the right call here.

Comment 2

[Ben Kero [:bkero]]

dhcp/dns entries queued up for when yellow flag is raised, will commit tomorrow

Comment 3

[Ben Kero [:bkero]]

I've created a CentOS 5.5 VM for this, however since buildbot-master4 already exists and is up, this is has a DHCP-assigned address from the pool.

You can reach it at:
root@10.12.51.235

If this is going to be a more long-term situation I can put a static entry in dns/dhcp.

Can you e-mail me the root pw for this?

Comment 5

set to current build password

I managed to get logged in, hooray! Performance seems decent enough (120MB/sec), so let's go with this for now. Can you update the DNS entries to point buildbot-master4 at this? I can't even access the existing machine at that name....

[Ben Kero [:bkero]]

Ok, the switch-over went perfectly.  Just updated a single DHCP record and ran dhclient, now the box is up at:

buildbot-master4.build.scl1.mozilla.com

[Ben Kero [:bkero]]

handed this off, confirmed good on irc, feel free to confirm here if you like too

I can't see any DNS entries for this at all:

It should have:
buildbot-master4.build.scl1.mozilla.com (A record)
buildbot-master04.build.mozilla.org (CNAME to the above)
Reverse DNS pointing to the scl1 name

Sorry about that, I reused the old buildbot-master4 DNS entry, which zandr later repurposed back to the original host.  I thought the old hardware was gone permanently.

I've created some new DNS records, and altered the DHCP records.  The host is online now, please confirm.

[bkero@boris ~]$ host buildbot-master4.build.scl1.mozilla.com
buildbot-master4.build.scl1.mozilla.com has address 10.12.48.18

[bkero@boris ~]$ host 10.12.48.18
18.48.12.10.in-addr.arpa domain name pointer buildbot-master4.build.scl1.mozilla.com.

[bkero@boris ~]$ host buildbot-master4.build.mozilla.org
buildbot-master4.build.mozilla.org is an alias for buildbot-master4.build.scl1.mozilla.com.
buildbot-master4.build.scl1.mozilla.com has address 10.12.48.18
