Todo

411 tools

  • fix ganglia to recognize broadcasts & update

Naming scheme

  • bs* vs compute-*-* vs c*-*
  • This is terrible it needs work

Updating bobsced0's RPM repo

  • yum-- free
  • up2date-- RHEL
  • "Aborting the rocks-update tool while the tool is downloading RPMs might produce corrupted RPM packages (SDSC Toolkit)" from pr_troubleshooting.doc

NIS map

  • /etc/passwd & /etc/group permissions

What broke cluster-fork?

Howtos

Updating nodes to be kickstarted & adding new packages

  • bobsced0 can be updated by just installing rpms
  • Check for an RPM in: /state/partition1/home/install/rocks-dist/lan/x86_64/RedHat/RPMS/
  • Edit /home/install/site-profiles/4.1.1/nodes/extend-compute.xml
    • Add a package i.e. <package arch="x86_64">libgfortran</package>
  • Update the files that get loaded on kickstart:
    • cd /home/install
    • rocks-dist dist
  • Check the kickstart file
    • dbreport kickstart c0-0
  • If there were no errors, kickstart the node. i.e.:
    • shoot-node c0-0
  • Check the progress of a kickstart
    • ssh –p 2200 compute-x-x

Adding post install scripts to kickstart

  • Edit /home/install/site-profiles/4.1.1/nodes/extend-compute.xml
  • Add a <post arch="x86_64"> entry i.e.:
    • <post arch="x86_64">cp /cluster/ganglia/gmond.conf /etc/gmond.conf</post>

Using 411 tools

  • make -C /var/411 on bobsced0
    • Copies the files to /etc/411.d/ using 411put
    • Notifies client nodes to run 411get using ganglia
    • The files that are watched can be updated by changing the makefiles in /var/411/
  • cluster-fork /opt/rocks/bin/411get --all

cluster-fork

  • Used to run commands on all cluster nodes like the c3tools
    • Broken, see todo
    • Temporary fix: cluster-fork --nodes="compute-0-%d:0-14" <command>

disabling reinstall (kickstart) after hard reset
