- Layout disk swap, new lo0
- HP Al-Salam switch enable jumboframes
Ongoing Projects (Spring 2017)
TODO
- EMAILING ALL THE USERS https://wiki.cs.earlham.edu/index.php/Sysadmin:Old:Contacting_All_Users
- SHUTDOWN SCHEDULED FOR SUNDAY (APRIL 16)
- Check/update instructions - one version is at https://wiki.cs.earlham.edu/index.php/Sysadmin:ImportantInfo:PowerFailure, there are others too
- Notify users
- Fix certs for gitlab, etc.
- Secure 1-2 admins for the summer
- Prep layout for May-June usage
- Practice shutdown-startup procedure (with Michael)
- Nsswitch consistency across all machines
- Document tools: startup / shutdown - Charlie
- Use Sysadmin namespace for all our pages - All
- Testing usefulness of documentation - Dave
- Al Salam: configure switch, re-rack. - Vitalii
- HP switch should be reset and tested.
- LDAP cleanup of system users / old groups - James
- Layout - Nirdesh
- Lo0 RAID (mdadm)
- 10GB from Dali to lo0 (adding rules on compute node routing tables as a possible fix)
- BIOS reset
- 10Gb, perfsonar, ...
- Monitoring: (Ganglia, Shinken)
- Getting consistency among all the machines(check_nrpe regularly stops working).
- Whedon: configured and available
- Change passwords (on everything). Postgres, shenken, ...
- Webcam on office whiteboard (new office location?)
- Learn virtual machine architecture and modules - Dave
- Document in a format for future admin training?
- Find existing introduction material
- Mirror control for testing, swapping, etc.
DONE (19 Jan 2017)
- Examine extra "layout" node. - Adam
- Differences are: Single PSU, Single GPGPU, No VGA.
- It has Infiniband and 10GB cards installed.
- Networking - Adam, Charlie
- IP over Infiniband working on layout
- Resolved by resetting IB switch configuration:
ibwarn: [3349] mad_rpc_rmpp: _do_madrpc failed; dport (Lid 1)
- Resolved by resetting IB switch configuration:
- IP over Infiniband working on layout
FUTURE
- Centralized password database / manager / location
