MPU Meeting Tuesday 11th March 2014

Inventory

Alastair has incorporated Chris's comments into TartarusWorkFlow. Stephen has no more comments.

Virtual DICE

Toby has made LDAP changes but not yet changed the ACLs. Once he's done that Chris will test Virtual DICE logins from EdLAN.

LCFG client refactoring

No activity.

Systemd

No activity.

LCFG port to RHEL7 or similar

Chris has been blogging his Fedora 20 progress in the SL7 port diary. The next stage is to get updaterpms managing the RPMs on an F20 machine, with its RPM list coming from an LCFG profile. Once that's done we should all be able to install an F20 VM with a minimal install, add the local yum repositories trivially, then fire up the client and updaterpms and have the package and component configuration automatically managed from then on.

Miscellaneous development

  • Alastair has fixed the updaterpms LCFG status check script.
  • Chris has changed the background for the login screens in the student labs to this. The survey closes on 30 April and the screens will be set back to normal shortly afterwards. (RT66025.)

Operational

  • When Stephen shipped the LCFG client update a few related problems had to be fixed - for instance the install profiles and PXE install images had to be changed.
  • Chris has done his pandemic topics and Alastair is working through his.
  • Chris has concluded that "HP Passport" is not relevant to DL180 firmware updates. He'll ask the IT Forum what other people have done.
  • Alastair and Stephen's latest theory about RT65774 is that it works fine until the user logs into a single-screened machine at which point gconf messes up the configuration. The solution would therefore be to set things correctly conditional upon hostname in the startup scripts.
  • Friday's fibrechannel switch failure made it evident that check_multipath no longer flags up the failure of a path. We'd like to know why. Also it would be good to know why the card on budapest could no longer talk to one port. Stephen will try a different card.
  • Stephen reminded us of the need to check file anomalies mentioned in the rkhunter reports and periodically update the stored file properties, as described in his rkhunter component documentation.
  • There's a problem affecting OpenAFS with recent RHEL kernels (408 series onwards for RHEL 6). It's triggered when volumes are multiply mounted on different paths, which is alien to the Linux kernel way of doing things. We don't do that much so shouldn't be badly affected. One problem area might be the package directories so we will refrain from updating the kernel on brendel for now.
