874015 - Please reimage sea-master1

Status: RESOLVED FIXED

Ok, so this bug has a few requests (that I can rip out to seperate bugs if need be, just tell me dividing lines)

1) undo the DNS confusion
 -- cb-seamonkey-linuxmaster-01 and sea-master1 have had DNS entries flipped.
 -- currently (internally on jumphost) cb-seamonkey-linuxmaster-01 points to 63.245.223.98
 -- currently (internally on jumphost) sea-master1 points to 63.245.223.11
 -- currently (external-to-jumphost) cb-seamokey-linuxmaster-01.mozilla.org points to <nothing>
 -- currently (external-to-jumphost) seamonkey-clobberer.mozilla.org points to |sea-master1.community.scl3.mozilla.com [63.245.223.11]|

 * expected result
 ** on jumphost sea-master1 points to 63.245.223.98
 ** external to jumphost seamonkey-clobberer.mozilla.org points to 63.245.223.98
 ** on jumphost cb-seamonkey-linuxmaster-01 points to <nothing>
 ** all netflows flows that exist for 63.245.223.11 // cb-seamonkey-linuxmaster-01 remain in place for 63.245.223.98 // sea-master1
 ** any flows that get severed be enumerated here or in e-mail to me for sanity check.

2) reimage sea-master1 63.245.223.98
 -- this should be CentOS 6.2 x86_64, (cpu/ram should not change from existing allocation, which I think is currently 2cpu, but RAM unsure)
 -- Based on https://wiki.mozilla.org/ReleaseEngineering/PuppetAgain/Base_Images
 -- see me or :dustin for help with this if confused.
 -- if we have a MoCo-based VM of this, that would be ideal/easiest, just needing networking and passwords set manually after we create the initial image.

3) system to be halted and handed to :gcox for VMWare alignment before being handed to me.

-------------
This setup is intended to replace the now dead parallels1.community and needed for SeaMonkey to be able to release our software.

Urgency is low, since I won't be able to begin using this until at least June 1'st.

Ok, I just had a brief convo about this, and I think I may have totally confused myself a bit, since now, 5 minutes after hanging up my phone I don't know what I just asked for :(.

Anyway, 

sea-master1 points at 63.245.223.11 in DNS, this is correct

the *VM* of sea-master1 is currently setup to have IP 63.245.223.98 -- this is not correct.

On reimage sea-master1 should be at 63.245.223.11 which is where all flows currently exist.

cb-seamonkey-linuxmaster-01 [currently down] is actually at 63.245.223.11, while its DNS points to 63.245.223.98 -- this will not be coming back so the IP for the above (63.245.223.11) is actually free for the taking, and we'll retire the IP 63.245.223.98 from our use.

----

Hope that matches what I just discussed, if it doesn't hope this doesn't confuse more and actually helps.

and yes this contradicts c#0, but after sitting and thinking about it, and how flows/etc are setup, this is the right thing and c#0 was wrong, likely explains why c#0 was confusing.

Current VM information:
Hostname: sea-master1.community.scl3.mozilla.com
CPU: 1
RAM: 2G
Disk: 50G

Proposed NEW VM will be:
Hostname: sea-master1.community.scl3.mozilla.com
CPU: 1
RAM: 2G
Disk: 40G

Which fits under our standard VM deployment.

Looks good to me.

sea-master1.community.scl3.mozilla.com is online @ 63.245.223.11.

Vanilla CentOS 6.2 x86_64 install done and VM is aligned.

Do you still need the DNS changes to be done?

[Adrian J Fernandez [:Aj]]

Forgot to add, previous vm renamed to:
sea-master1.community.scl3.mozilla.com-Bug874015

Please let us know when we could delete it.

Comment 7

[Adrian J Fernandez [:Aj]]

As per IRC, not DNS changes needed and previous VM deleted.

You officially became the Seamonkey guy in our team. Congrats! :D
