Tickets resolved since last report.

Some of these topped the "blockers" list until they were resolved:

Blockers?

These tickets are not yet resolved and have several other tickets depending on them. If one of these is yours, see if you can do something to help the dependent tickets along.

Progress by unit

User Support

  • The student and staff compute servers were upgraded. User Support tracks its upgrade progress at Sl7USUnitUpgrade.
  • aristo, lindor and zondar have now been removed.

Research and Teaching

RAT has recently been concentrating on the start of session, so SL7 work has mainly consisted of further enhancement of software packages and tidying of headers and package lists.

Managed Platform

  • Both PXE / package cache servers have been upgraded to SL7.
  • The two new KVM servers (gaivota, girassol) are running SL7 and are in service, hosting VMs. We're fleshing out plans for upgrading the rest of the MPU's KVM servers.
  • The NX servers were upgraded to SL7 a while ago.

Infrastructure

  • Testing prometheus with the latest Moose, with mixed success - specific problems seem to have been introduced by changes to the meta-object framework made between 2.1005 and 2.1804.
  • openldap headers have been revamped somewhat, and 3 new LDAP servers installed (but not yet put into service)
  • Several tickets closed (see above): lcfg-nut, dice-nut, forum-server-room.h, at-server-room.h.
  • Started upgrading console servers to SL7. One current 'stopper' is behaviour of KVM guests which have multiple NICs: we need guidelines for the creation and consistent naming (i.e. across reboots) of those interfaces. MPU aware.
  • IMPORTANT: all Units need to ensure that all SL7 services are satisfactorily tested for their behaviour in the absence of an LDAP service (see Section 3 of the 'Final report' for the 'OpenLDAP: DICE client configuration' project), and that specific servers are then special-cased as LDAP slave servers if and as necessary.

Services

  • SL7 AFS server "gresley" is now in service.
  • We've increased our number of in service SL7 servers 400% . We now have 5 AFS servers - gresley, nix, kelpie, naga, cetus !
