MPU Meeting Tuesday 2nd November 2010

LCFG Server Refactoring

Stalled.

Software Build Farm

Stephen reported that documenting the database layer was now finished. He is now looking at the daemonized processes. The build daemons now run without actually executing mock. There are issues with Perl signal handling, timeouts etc and this requires care to make it robust.

F13

This is now closed.

Replacement for VMware Server

Alastair has created a homepage for the project. This needs to be published and discussed. It may be that we want two services. Since 'live migration' is hard and would increase the project time then we may be able to use the IS service (assuming it is suitable) for those services that require it. Replacement of our own VMware service should give us better manageability and peformance for local virtual servers. We should evaluate IS's service.

Review Project List and Prioritise.

There was a long discussion on the current and pending projects for the next project prioritisation round.

  • RHEL 6 based distribution : it was agreed that this project would be a main priority.
  • Build Farm : should be finished by Christmas, thus allowing us to revive...
  • LCFG server refactoring : as a priority for T1-2011
  • Virtualisation : even if we go the IS route for some VMs this project still needs effort.
  • Install scripts for self-managed : evaluate requirements, was down for T3-2010.
  • Fstab enhancements: raise the priority of this project. Potential joint project with Kenny at IS. Use Perl not C.
  • Evaluate non-RHEL based Linux distributions : no time.
  • LCFG documentation technology : no time
  • Logserver enhacements : schedule after the LCFG server refactoring.
  • Automated upstream package monitoring : Perdita is keen to see something like a web front end so we can see what packages are installed.
  • Virtualised DICE image : (Takeaway DICE) this will involve moving around large quantities of data.
  • Package submission enhacements : Chris is doing this ?

It was pointed out that 'user visible' projects should be given a high priority if possible and

Miscellaneous Development

Patch to pkgsubmit
to prevent submitting a file twice

Operational

Panos's request
no action

Moving sauce to KB

Stephen had circulated a message about a kernel bug. RHEL fix awaited, fix when it comes.

Memory problem
R710s : Chris has phoned Dell

F12 package list
removed, but 3 hosts still complaining :
