752531 - migrate dev-stage01 to scl3

Status: RESOLVED FIXED

(Infrastructure & Operations Graveyard :: CIDuty, task)

Description

[[e-mail] (:bhearsum)]

Needs to move before sjc1 goes away. We need to update the buildbot-configs to point at it, adjust post_upload.py on the machine after migration, update known_hosts, and possibly a couple of other things. bug 739778 can probably be used as a guide for the releng work.

update ssh-config package

Can you also bump the version number of the packages (ssh-config{,-staging}?

Also make sure to add the entry to known_hosts files on the puppet masters under /N.

Landed, updated packages, and set to rollout to build machines.

Is there a reason why we're using the specific host name in scl3 in the configs vs just using the alias (dev-stage01.build.mozilla.org)?

I suspect it harkens back to the conversation we've had (at least twice since I've been here), that the bmo CNAMES are for human use only and shouldn't be in configurations or used by machines?

yes

I won't rathole this bug with that discussion. Someone can educate me privately about why that's preferable.

I added the new hostkey entry to all of the known_hosts files on the puppet servers (scl1, scl3, mv), too.

Left to do here: update buildbot-configs after the machine actually migrates.

Comment 12

[[e-mail] (:bhearsum)]

Oh, also need to make sure it connects to Puppet alright after the hostname change.

update buildbot-configs

Landed this on default.

Your changes on default are now on the production branch and the masters have been reconfigured around 8AM PDT.

Can anyone reach this host?
