MPU Meeting Tuesday 19th July 2016


Nothing happened due to holidays.

LCFG Client Refactoring

Package name changed to "lcfg-core".

Stephen has been researching documentation tools and has selected doxygen which seems to handle C code quite nicely, it can generate html and latex formats. Stephen has begun documenting the libraries to see how well it goes.

There has been more testing of the Perl interface. Support for dumping profiles and components as hashes has been added to make debugging easier.

LCFG::Utils and updaterpms
Tweaked versions built against the core library

Now have a running rdxprof on circlevm5. The change handling has seen a lot of work and seems to do the job properly. Some of the tests have been updated, much more testing required though. Stephen has seen the occasional strange crash of the master daemon process, not clear if this indicates a bug in the way it forks/waits for the build and fetch child processes.

MPU SL7 Server Upgrade

Alastair will check the NFS component and configuration.

Stephen will talk to George about IPv6 addresses and get those organised before doing the upgrades of the SSH servers.

Stephen will talk to Neil about mod_waklog

Miscellaneous Development

Build tools
Stephen has done some further work on the build tools to add support for doing CMake builds in a directory which is different from the source directory. Along with this the lcfg-om package was updated to fix the build scripts.

The default configuration for xinetd on SL7 has been changed so that the system defaults are used, see bug#341 for details. We should push this change down to the lcfg-level, Stephen will check that is safe at the next Deployers Meeting.

Sleep component
Chris has been working on fixing bugs in the sleep component and making it quieter for rootmail. In particular he has dealt with problems with USB devices preventing sleep which can sometimes only be cleared with a hard reboot.

HP EliteDesk 800 G2
The G2 still does not sleep properly, the display never comes back. We will disable it for now and hope that a later kernel update fixes the problem.

Ian and Chris have looked at the latest iDRAC in the Dell PE R730. We should decide whether to use the dedicated interface or the shared interface. What are the pros/cons of each approach? Still need to look at whether this offers a better way to handle firmware upgrades. How should the web interface be accessed? Are there instructions?

Lenovo P310
We now have a P310 running SL7. It all seems to work fine, the onboard intel graphics are fine. We're buying the students machines with nvidia cards but that shouldn't cause any problems. The configuration includes a 1TB SATA disk and a 250GB SSD. Alastair has been investigating doing the system install onto the SSD. To handle encrypted partitions properly we will need a new fstab component resource for setting "crypt options" for a partition which is mounted via crypttab. We will also need to be able to tune the swappiness to avoid unnecessary use of the swap partition.


dice installbase
The dice installbase profiles were restricted to which didn't work for machines without DNS entries. The access has now been changed to being IP-based.

The failed disk in the KVM server oyster has been replaced.

R330 and R430
Chris is happy that the new server models work properly with LCFG.

New KVM servers
Can begin installing gaivota as a KVM server. We discussed possible partition layouts, will want a good chunk of space for the libvirt partition for suspending VMs. To keep things simpled we will just have one big pool.

waterloo console
The KVM server waterloo lost its serial console again, this might indicate a duff BMC. The recent power outage in AT cleared the problem. It might be worth moving the console to the serial port connected to a Lantronix box so we always have reliable serial console access.
