SL7 Server progress to 5th of December 2016
The table and graph at the top of this page summarise the entire progress from the start of the SL7 server project to the 5th of December.
The rest of this page concentrates on progress since
the last report.
Since the last meeting 7 tickets have been created and 27 have been resolved. Infrastructure and Services have resolved two each and the MPU has resolved 23 tickets.
Tickets resolved since last report.
Blockers?
- Some Infrastructure upgrades are being blocked by a bug affecting servers with NICs configured for multiple networks. So far the behaviour has been difficult to reproduce. However Stephen has a theory as to what might be going wrong and how it might be fixed.
- 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
No unit is going to finish by the end of the year, but several think they'll finish the server upgrades early in 2017.
User Support
User Support has recently upgraded castor, pollux, selma and patty, with salmon and trout scheduled for Thursday.

Research and Teaching
RAT has quite a few services which are
almost upgraded. They expect to finish early in 2017.

Recent work includes the completion of the upgrade of the KVM servers, and the move of BuzzSaw and the Log Cabin service to SL7. Work is currently concentrating on the upgrade of the LCFG master server and of the remote wake-up service. Most MPU services are now on SL7, but perhaps inevitably, some of the most difficult work has been left until last, so the MPU is unlikely to meet the end of year deadline.
Infrastructure
Some of the Infrastructure Unit's SL7 upgrades have been delayed by a networking bug affecting machines with multiple interfaces. So far the buggy behaviour is proving difficult to reproduce reliably.
