Split carbon's install/mirror roles, provision install1001
Closed, ResolvedPublic
Actions

Description

OK, so we have a few things in-flight right now (e.g. jessie upgrades, T132450/HTTPS for carbon etc.), so it's about time to clean this all up.

This would be my suggestion:

  • Upgrade install2001 to jessie, make sure our manifests work there (trivial)
  • Deploy a new install1001 VM
  • move install_server (DHCP, TFTP, preseed web) to install1001
  • move reprepro/apt (remember /root/.gnupg/!) to install1001
  • Remove all install_server-related roles out of carbon and designate it as a mirror server (T84817); reinstall carbon with jessie (T123733)
  • (optionally) split the reprepro role out of install_server in puppet, they're really different roles
  • Upgrade install2001 to match install1001 (i.e. add DHCP, point codfw's DHCP relays to install2001) (T84380)
  • Set up apt on install2001 too (sync done with rsync in cron)
  • use a reprepro hooks to sync apt across and possibly make apt.wikimedia.org HA (perhaps with gdnsd). -> (T158022)

Any takers? @Dzahn maybe?

Dzahn added a subscriber: akosiaris.Dec 21 2016, 8:45 PM

so current status is now:

if in public1-b-eqiad or public1-c-eqiad then install1001 is used for everything (DHCP -> TFTP -> serves installer), if in other subnets we still use carbon as DHCP but then TFTP is also install1001 already

Dzahn added a comment.Dec 21 2016, 8:48 PM

other things we need:

  • move ganglia aggregator
  • change ACLs / ferm rules for webproxy
    • (it's still webproxy 1H IN CNAME carbon.wikimedia.org. in DNS)
  • rsync apt repo again
  • confirm if we still want to reinstall carbon as a "role mirror" as the ticket says or if that is already done because sodium is now a mirror and we just decom carbon
  • ?

In T132757#2894515, @Dzahn wrote:
  • @akosiaris configured switches so that public1-b-eqiad and public1-c-eqiad are using install1001 as DHCP

Correction: private1-c-eqiad, private1-b-codfw

so current status is now:

if in public1-b-eqiad or public1-c-eqiad then install1001 is used for everything (DHCP -> TFTP -> serves installer), if in other subnets we still use carbon as DHCP but then TFTP is also install1001 already

Same correction here as well.
