Welcome to the Georgia Advanced Computing Resource Center wiki. The information provided here is a supplement to the GACRC webpage.  The GACRC online information resources include:
"W" means "don't know When this task will be done"
Soon: /etc/motd on pcluster, zcluster
========================================================================
Wednesday:
Morning: GD message to users
2 PM: CC VM snapshots
3 PM:
  PB disable logins pcluster: restrict_sshd
  PB disable logins zcluster (except for jkissing, students): restrict_sshd on zcluster
  PB kick users off pcluster
  PB kick users off zcluster but not jkissing or students
  PB drain all nodes or queues, pcluster: llctl -g drain
  PB disable all queues except somedevq, zcluster
  PB kill all jobs pcluster: llcancel $(llq | grep -w R | awk '{print $1}') 2>&1 | tee llcancel.log
  PB kill all jobs zcluster: qdel $( qstat -s r | egrep '^1' | awk '{print $1}') 2>&1 | tee job.qdel.log
  JS move some rack15 nodes to rack 16?
  do GE jobs testing MPI and storage I/O throughput
    CC to use fsr15 for iozone
    ST to use fsr12 for MPI/NAMD
    PB to use fsr7 for dumb I/O
  PB stop execd on all nodes, zcluster: qconf -ke all 2>&1 | tee qconf.ke.log
  shut down racks 8,9,10,11
   
4 PM:
  CC reconfigs NICs/LAGs on storage units
  PB modify PanFS blksize on remaining nodes
  CC shut down VMs (wait for Jessie off zcluster)
  shut down 3070s (umount first)
  PB shut down Panasas (umount first)
  CC connect ESX IPMI cat5
by 5PM:
we tell NEG "go ahead"
CC recable storage unit cat5, and work with Brian M on switch port configs
probably between 9 and 12PM, NEG finishes
