Bobsced

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?

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

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>

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

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>
