MPU Meeting Tuesday 6th June 2017


The ii query command now supports specifying multiple fields for output using the --fields command line option.

Alastair has added a "wandering time" report using the new client report. Stephen suggested checking that it's acceptable to send emails from postgres@inf and that any bounces go back to somewhere appropriate.

LCFG client refactoring

Stephen has been working on adding support to the new Perl libraries for the qxprof and sxprof tools. In particular these tools need to able to read/load resource information from multiple sources and then merge them. For backwards compatibility the plan is to add support for specifying resources in the old hash-ref style.

MPU SL7 Server Upgrades

The final report is done and Alastair has announced to COs that we are putting the project forwards for completion at the Development Meeting.

Additional disk encryption

The prioritisation meeting has decided that we're going to skip the intermediate project and wait for the arrival of the new encryption technology in SL7.4. In the meantime Chris will look at the beta to learn more about the technology but not do any development work.

Miscellaneous development

DICE desktop review
Alastair has been working on a review of usage for the DICE desktops, this is based on wtmp login information. The idea is to summarise the usage for time slots through the day.


The disk has been wiped and the cabling removed. Chris is awaiting better weather before bringing it back to the Forum junk room.

SL7.3 reboots
The staff SSH server brendel has been done, the main server bruegel will be done on Friday.

The new version has been tested and seems to work as required, Stephen will update the version on the wiki page and announce it to Support.

rhel6 VM console
Alastair has fixed the serial console for the rhel6 VM, he wonders if it will break again the next time there is a kernel upgrade.

Disabling kernel module loading
Alastair successfully tested this with drupal on the development VM for

Latest qemu version
Chris has tested the latest ev version of the qemu packages on _circle. We should update the rest of the KVM servers when they are upgraded to SL7.3

jubilee BMC
We should fix the address for the BMC on jubilee when we reboot it for the SL7.3 upgrade.
